CCIE Routing and Switching Practice Lab 3: The VPN Lab

Herein, you would be through the equipment requirements and pre-lab tasks in preparation for taking the VPN practice lab.

The CCIE Routing and Switching Lab exam would be commenced with 2 hours of troubleshooting which would be again followed by 5 1/2 hours of configuration and ends with 30 minutes of additional questions. This CCIE Routing and Switching Lab have been timed to last for 8 hours of configuration and self-troubleshooting, so as to aim in order to complete the lab within this period.

Then either score yourself at this point or you might continue until you feel that you have met all the objectives. Now, we are going to guide you through the equipment requirements and pre-lab tasks in preparation for taking this CCIE Routing and Switching practice lab.

If you don't own six routers as well as four switches, consider using the equipment which would be available and additional lab exercises as well as training facilities that could be found within the CCIE Routing and Switching. But before that, if you wish to practice this in detail, you could do it by gaining access to the prep courses of SPOTO.

Equipment List:

You would be needed the following hardware as well as software components in order to begin this practice lab:

•    Six routers loaded with Cisco IOS Software Release 12.4 Advanced Enterprise image and the minimum interface configuration, as it is being documented in Table 3-1

Table 3-1. Hardware Required per Router

Router    Model    Ethernet I/F    Serial I/F

R1    3825    1    1

R2    3725    —    2

R3    3825    —    2

R4    3825    1    1

R5    3825    1    1

R6    3825    2    —

The 3825s used in this lab were loaded with c3825-adventerprisek9-mz.124-6.T.bin, and the 3725 was loaded with c3725-adventerprisek9-mz.124-6.T.bin.

NOTE

The 3550 in this lab was loaded with c3550-ipservicesk9-mz.122-25.SEE.bin and the 3560s with c3560-ipservicesk9-mz.122-25.SEE.bin.

•    One 3550 switches with Cisco IOS Software Release 12.2 IP Services and three 3560 switches with Cisco IOS Software Release 12.2 IP Services.

Lab Topology

This practice lab uses the topology, which you must re-create with your own equipment.

Switch Instructions

Configure VLAN assignments from the configurations which would be supplied on the CD-ROM or from Table 3-2.

Table 3-2. VLAN Assignment

VLAN    Switch1    Switch2    Switch3    Switch4

45    Fa0/4, Fa0/5, Fa0/6    —    —    —

200    Fa0/19    —    —    —

400    —    Fa0/19    —    —

Trunk    Fa0/1    Fa0/6    —    —

Trunk    Fa0/20    Fa0/20    Fa0/20    Fa0/20

Frame Relay Instructions

Configuring one of the routers you would be going to use in the lab as a Frame Relay switch or would be having a dedicated router purely for this task. This CCIE Routing and Switching lab would be utilizing a dedicated router for the Frame Relay switch. A fully meshed environment is going to be configured between all the Frame Relay routers. Pay attention in the lab as to which PVC (permanent virtual circuits) is actually going to require. You are needed to keep the encapsulation and LMI (Local Management Interface) settings to default for this exercise, but experiment with the settings outside these labs because you might be required to configure the Frame Relay switching within your authentic lab.

If you are going to utilize your own equipment, keep the DCE (data circuit-terminating equipment) cables at the frame switch end for simplicity as well as provide a clock rate to all links from this end.

So, here you have basic knowledge, about what you would be needed in the CCIE Routing and Switching Practice Lab, but, knowing and doing is a totally different thing, thus, your next step would be to practice it on real or virtual equipment. I would say that if you wish to have such a practice, you could gain it on the SPOTO.

Talking about the Network Deployment Model of the Double Center in the Same City

When an enterprise builds a data center, two or more data centers will be built for disaster recovery considerations. For example, we often refer to the "three centers of the two places", that is, the same city double center + off-site center.

The same city dual center refers to the establishment of two data centers that can independently undertake business in the same city or neighboring cities. The dual centers have basically the same business processing capabilities and synchronize data in real time through high-speed links. In daily situations, the business and management systems can be shared simultaneously. The operation, and can be switched to run; emergency backup in case of disaster, to ensure the continuity of the business. The remote disaster recovery center refers to the establishment of a backup disaster recovery center in a remote city for data backup of the dual center. When a disaster occurs in a double center due to natural disasters, etc., the remote disaster recovery center can use the backup data for business. restore.

Today, I mainly talk about the network deployment model, switching methods, advantages and disadvantages of the same city dual center.

There are two deployment methods for the dual-center in the same city, which are mainly active and active. You can visit SPOTO to get more information.

1. Active and standby center model

From the literal point of view, the main and standby center is to build two data centers, one master and one backup, both data centers have the ability to independently provide external services. Under normal circumstances, the main center provides external services. When a major fault occurs, the main center's business is switched to the standby center, and the backup center becomes a new production center to provide external services.

The above description of the master-slave relationship is very simple, but in the actual deployment process, network, application, database, and other departments need to coordinate and cooperate to switch. We mainly talk about the network today.

Schematic diagram of the active and standby data centers:

Ac.pngac.png

The figure above is a typical network model of the main city center in the same city. The center A is the production center, the center B is the standby center, and the business divisions of the two centers A and B use the same IP address segment.

The technical key points of this model:

1. The network core (gateway) of the A and B centers are opened on the second floor;

2. The gateway is enabled on the main center side, and the standby center gateway is in the off state;

3. The primary center A advertises routes to the outside, and the B center does not advertise routes.

Switch between data centers:

The A center stops issuing routes to the outside, and the B center switches the gateway of the A center to the B center at the same time, thus completing the switching of the data center network.

Advantages of the master and backup models:

1. Simple technology and convenient switching;

2. The existing dual-center transition to this model is relatively simple and does not involve the application IP address transformation;

Main and standby model disadvantages:

1. There are many inter-center traversal traffic, and it is impossible to “the central server enters and exits from the center” (the gateways on both sides cannot be opened at the same time, otherwise the firewall asynchronous routing problem will occur).

2. The physical distance between the centers is too long, resulting in increased network delay, and delay-sensitive applications may be affected;

3. When the center L2 is opened, the Layer 2 domain will be expanded. One central Layer 2 fault may affect another center. Data center STP isolation or special technology, such as OTV, is required.

4. Consider the issue of how firewall policies are synchronized;

5. The link is idle and the resources are not maximized, such as the external WAN link of the B center.

2. Double live center model

Double-active data centers, that is, two data centers have the ability to provide services simultaneously. As shown below:

B.png

The two data centers A and B use separate IP address segments and provide services to the outside. The client relies on the DNS analysis results to determine which data center to enter.

The technical key points of this model:

1. The two centers use separate IP address segments, and all routes are advertised.

2. Use DNS to direct client traffic to the corresponding data center.

Data center switching:

1. Under normal circumstances, two data centers provide services at the same time;

2. When the data center fails on one side, change the DNS resolution to stop the service in the data center.

Double live data center advantages:

1. The two data centers are completely independent and do not interfere with each other;

2. Less traffic between data centers;

3. There is no need to consider the firewall asynchronous routing problem;

4. The link is more efficiently utilized and the economy is maximized.

Disadvantages of the double live data center:

On the technical side, there are no shortcomings. Feasibility, from the existing dual-center to the double-active data center, in addition to the IP address transformation, it also involves the application of DNS transformation, involving inter-departmental collaborative work, driving difficulties, this model is more suitable for new data centers.

Choosing a data center network model requires investigating the deployment requirements of the business/application/system/server, and considering the top-down unified considerations, the best for you is the best.

Remarks: Whether it is active or active, it is not difficult to achieve various "lives" at the network level. In the production environment, the biggest bottleneck currently faced is actually the "double live" problem of the dual-center database.

My experience of learning CCNA to CCIE

When I first learned CCNA, I was a little scared, because when I first learned about the configuration manual and study guide, it was just a lot of commands and some knowledge that needed to be understood. After learning CCNA, I start CCNP curriculum, which is harder than CCNA, also need to spend more time.

When I started to learn CCNP, my learning is poor, CCNP is more experimental than CCNA, and because my naughty often fail, so the completion of the experiment also needless to say, at that time I also signed up for SPOTO BOOTCAMP classes during the summer.

Now think back to the BOOTCAMP course at the time is still very useful, such as the project drill course, we are divided into 4 groups, the project bidding simulation, during the learning how to make PPT, draw network topology, etc., these will be used in corporate work, There are also some very useful courses in AAA, ACS, IOS upgrade, device password recovery and so on.  

When I finished the BOOTCAMP course, I took the CCNP certificate in the third year of my junior year, and then I left the university for an internship. During this period, I interviewed several companies, but I did not go because of the low salary. In march, after I return from shenzhen to fujian, formally started in fuzhou CCIE study course, first of all, I said I'm CCIE study method, I was a full-time study, there are a lot of learning time, in every time before class, I will go over the CCIE thematic teaching video, and using the word record notes, write down do not understand the problem first, and then ask the teacher.     

It took me about eight hours to practice the version for the first time, and I had to say it was a bit of a blow to my confidence, but I didn't give up, so I typed it almost twice a day, and it was a little bit slow at first, almost always until about two o 'clock in the middle of the night, sometimes even longer. In this way, after about 16 practices, I could control the version time to about 3 hours only based on the demand. Some people may worry about the 3 hours for a long time. In fact, most of the examination rooms are preconfigured.      

For TS on this, my conclusion is: follow the teacher's training video is no problem, if you can in a few minutes, the test is no problem, the teacher training has been contains all possible fault point, anyway, that's what I do, one thing to note is that never rote learning, be sure you understand!!!!!      

After more than a month of hard work, I finally went to the examination room. A few days before the examination, I did not do any more exercises. I just watched the examination room feedback and collected information. The change was not very big. The fault diagnosis changed, but my teacher gave Solved, the teacher is very powerful. The day of the exam was also very smooth. There was no change. It was similar to what I usually practiced. The version I was pumping was H1+, the spanning tree was H1, and I finally got my CCIE number.

What Is the Difference Between CCIE RS and CCIE Security?

Well, CCIE Routers and Switching would be considered as an evergreen track. But at the same time, the importance that the CCIE Security track has, wouldn’t be denied as the value of it, is almost same as the value of CCIE R&S, which again would make it a bit complicated for the fresher to differentiate from.

After going through this whole article, you might be able to specify which course or track among the two would suit you best to him or her for their future specialization of CCIE. Before moving to the list of the facts, it would be good to make a thorough comparison of the outcome obtained with both of these tracks.

Career Scope of CCIE R&S and Security:

CCIE R&S:

It is a surprising fact to note that the industry demands for around 300,000 CCIE Routing and Switching certified professionals, whereas it has only 35000 active professionals as on date. This speaks about the untapped market and the huge skill shortage. As a layman, we all know that with the demand and supply imbalance, where demand is higher than the supply, we have the opportunity to encash it for high packages for respectable positions in the networking domain.

CCIE Security:

The challenging era of digitization and internetworks, there is a strong demand for expert IT infrastructure professionals who can design, administer and maintain secured networks ensuring smooth functioning throughout the enterprise environment. According to the stats, there are only 6000 security professionals while the demand is nearly around 200000 which is an amazing opportunity to have a secured career with a great future.

Expected Job Roles and Growth opportunities

CCIE Routing and Switching:

After completing CCIE Routing and Switching, you get eligible for promising career profiles of:

•    Network Engineer

•    Senior Network Engineer

•    Network Administrator

•    IT Manager

•    Network Specialist

•    Principal Network Architect

Not only reputed designations, but CCIE Routing and Switching track can fetch you a handsome starting package of minimum $94,582 per annum.

CCIE Security:

CCIE Security certification opens doors to multiple profiles in the Networking domain depending on their skill sets. Let’s have a look at the Job Opportunities that you would have after CCIE Security:

•    Network Security Administrator

•    Network Security Engineer

•    Senior Network Engineer

•    Security Analyst

•    Network Security Engineer

•    Network Security Specialist

A CCIE Security certified fresher can expect a minimum salary of $101,039 per annum at the very beginning of their career.

CCIE Certification Road Map

For CCIE Routing and Switching, your learning starts with:

•    CCNA Routing and Switching

•    CCNP Routing and Switching

•    CCIE Routing and Switching

The CCIE Security certification journey is designed to up-skill your understanding and internetwork expertise. To achieve this level you start from here:

•    CCNA R&S (Associate)

•    CCNP R&S (Professional)

•    CCNA (Security Associate)

•    CCNP (Security Professional)

•    CCIE Security (Expert)

Note: It is a mandatory pre-requisite to have Routing and Switching knowledge for pursuing Cisco Security track.

If Networks fascinate you and you wish to master them, then CCIE is the best choice to make. Going by the opportunities and the pay scales, CCIE security supersedes the Routing and Switching track, but not to forget, CCIE security stands unachievable without an in-depth understanding of Routing and Switching.

So, whichever Certification, you like to go with, trust me; you are going to need lots and lots of studying and training to gain them. It would be thus recommended for you to gain the training which you could obtain through the well-reputed and reliable training providers like the SPOTO. When it comes to Cisco Certification and much more, SPOTO would be the best training provider for it.

CCNP Collaboration Interview Questions.

Before getting on to the CCNP interview questions, the candidates must know that the CCNP is considered as a continuously varying field which needs the candidates as well as professionals to upgrade their skills along with the new features and knowledge, to get fit for the jobs which would be associated with CCNP Collaboration. Below mentioned are some of the CCNP Interview Questions and Answers, which would help you to find all the solutions that would be frequently asked in your upcoming CCNP interview. You would also need to go through some expert training which you could gain it at SPOTO.

 CCNP Interview Questions and Answers

Q1: Describe why postal addresses, as well as telephone numbers, are routable.

A1: A postal address has three components that could be utilized to deliver mail: state, city, and street. A phone number has an area code as well as exchange. At the core layer, mail could be distributed to the subsequent post office which is based on only the state or city and state information. A phone number is going to be delivered at the core layer based on the area code.

Q2: What is the reason for a default route?

A2: A default route is utilized if there isn’t a specific entry in the routing table for the destination.

Q3: Differentiate between routing and switching.

A3: Routing moves a letter or telephone call to the access layer like in a street or telephone exchange. Switching would make the final delivery. A switching decision is made on the part of the address that isn’t utilized in routing like in the street number or last four digits of a phone number.

Q4: How does the use of a hierarchical routing structure would enable a scalable delivery system?

A4: If a delivery system isn’t divided into access, distribution, and core layers, every point in the system which would be needed to maintain every possible destination address to make a decision of delivery. The use of a layered system means that each layer would need only the information that would be necessary to deliver to the next layer, either above or below.

Q5: What are considered as the access, distribution, and core components of a postal address?

A5: The street name and number are considered to be the access layer components. The city name is considered to be the distribution layer component. The state name would be considered the core layer component.

Q6: What would be the main purpose of areas in OSPFv2?

A6: Routers networks are distributed into the areas which would be connected to the backbone area. The areas help you to give a performance as well as easy to handle the big network.

Q7: Mention the router types in OSPF.

A7: There are Internal Router, ABR and ASBR are the various types of the router in OSPF.

Q8: What would be the purpose of WEIGHT attribute on OSPF?

A8: There would be no attribute such as WEIGHT in OSPF.

CCNP Collaboration Conclusion:

Now, as and when you have gone through a basic list of CCNP Collaboration Interview Questions and Answers, you need to understand that there are lots more questions and answers that you need to know and that you would be able to do if you join the training courses provided by the SPOTO.

SPOTO is considered to be the one stop shop for the various IT related certifications, which could be gained along with the passing guarantee. At SPOTO, there are numerous experts, who have already gone through the courses, and would give you the updated materials, which would be quite helpful for clearing any of the Cisco Related Certifications.

CCNA Collaboration Certification Exam Preparation.

CCNA Collaboration is considered for the IP network engineers, IP telephony, and network video engineers who are aspiring to develop and advance their collaboration and video skills in line along with the union of voice, video, data, and mobile applications.

 Tips and Tricks to clear the CCNA Collaboration Certification Exam

Preparation Method

Now that perceive about the certification as well as the prerequisites; you might have a method for the preparation. You would have to cover all the topics which would be included in the syllabus of CCNA Collaboration. Take a print out of the syllabus as well as prepare an individual study method which would be based on this.

Conventional Study Time

During the preparation as well as when you are appearing for the exam, time management is considered to be important. Studying consistently so that whatever is studied would be retained in the memory. Allocate a definite time to study every day as well as make sure that you follow it.

Practice tests

There are plenty of practice tests on CCNA Collaboration available online. I would like to recommend you to take practice tests on various training providers like the SPOTO. Practice tests on this site would be quite helpful to them with many things. For example, you could formulate the theories into questions. The candidates are required to gain the knowledge of what all is required to answer the question and how much time they would require to write. This would be quite helpful for the candidates to learn the topics and they should also have the knowledge, their luck might favor, and the questions would repeat it.

Building a Lab

In the world of Networking, nothing could be acquired without practicing in the Lab. There is only one motto that would be required to be a real Networker. That would be, Study a Lab and repeat. Nothing could defeat this Motto. For every topic you would be studying, for every topic you understand; it cannot be acquired until you have practicing it in your CCNA Collaboration Lab on real Cisco devices. It is unfeasible to do Networking without its practical approach as every theory that would be needed to be explained to remember. Every CCNA Collaboration Certification requires about 1 to 2 hour of the precise hands-on session on real Cisco devices.

Reading Material

There are lots of materials available on the web from where you could learn about CCNA Collaboration and its concepts. But nothing could switch the Cisco Press books and your written notes from your training classes. Various books are going to lead you to spend more and more time on reading and understanding rather than studying and practicing. Having one reliable reference would be able to make the complete process simple.

Give Attention to Details

Learning the theory by-heart wouldn’t be considered to be beneficial you in clearing the exam. Learning about how things are done in Cisco. Sometimes, Cisco works differently than distinct scenarios. So, get to know about the methods which are being used in the Cisco environment. Cross-check every minute detail to reassure that you have not missed anything.

And the most relevant thing while you are going for the exam is to have a relaxed mind. If you are through with all the concepts and have taken efforts in trying out ideas for yourselves, it would be quite apparent to crack the certification.

CCNA Collaboration Certification is quite difficult to obtain, unless, you have a proper training provider, like the SPOTO CLUB. They have the best study dumps, which could be very much helpful for the candidates to gain their certification in a single attempt.

How to Prepare the CCNP RS Certification Exam?

 You are preparing for the Cisco CCNP R&S certification exams, and you might be wondering about how to make the best of your self-preparation, right? You don’t have to despair; there are many professionals who would have gone through the same process and would have been certified. All you need to do is to know the right steps in order to take towards preparing for the certification examination and be ready in order to take them effectively.

 Ways to Prepare CCNP R&S:

 •    Go through the CCNA Course again

First and foremost, it is very important for you is to go over the basics of the CCNA R&S course again in preparation for the CCNP R&S certification exam. This is because the Cisco Certified Network Professional Routing and Switching credential would be built upon the CCNA R&S concepts. The topics are the same, only that the CCNP R&S would treat a wider scope of them. No matter how well you would be thinking you know your CCNA R&S topics, it is very essential that for you to revisit them again. Going through the topics that would help you refresh your knowledge, skills, and competence that are considered to be demonstrating during the CCNA R&S certification exam.

 •    Being strategic about your study

It would be considered very easy to memorize your course materials with the hope of offloading it during the exam. Well, this is not going to work with the CCNP R&S certification examination. The CCNP R&S course is not something you could memorize. You need to study as well as understand about each of the topics, and the sub-topics in a comprehensive manner. It would be going beyond reading from cover to cover, page to page. You are required to make a conscious effort so as to understand each topic and be able to apply them.

 •    Use practice exams

Taking a practice test is also considered to be quite important for you to achieve success in the certification exam. By taking the practice exam, you would be able to know your strength areas and your weak areas. This would be enabling you to know where to dedicate more time while preparing yourself for study. There are many options for gaining with the practice exam from online resources. SPOTO, for instance, offers you the best study dumps, which is considered to be quite helpful in your preparation process.

 •    Plan your exams

The CCNP R&S certification has three distinct modules which are: 300-101 ROUTE, 300-115 SWITCH, and 300-135 TSHOOT. You could choose how you would be writing the exams. It doesn’t matter which you take first; you just need to plan out your time and study so as to be able to take all three within a reasonable time. According to CCIE experts, it is considered to be very much essential that you take the module that you feel is easy among the three for you. Passing a module would be able to boost your confidence for the other two modules. It would be considered quite crucial that you plan the sequence in which you would be writing the exam well ahead of your preparation and writing the test. This would be enabling you to plan out your study adequately so that you could have productive study time. Gaining CCNP Routing and Switching certification, you are required to have proper training module, which you could obtain through the training module provided by the SPOTO.

NAT64 Technology: Connecting IPv6 and IPv4 Networks

What You Would be Learning in this Module:

There are 3 main options are available for migration to IPv6 from the existing network infrastructure, dual-stack network, translation, and tunneling. Here we are going to briefly discuss all of these options as well as highlights the advantages of translation and particularly stateful translation, over the other two. 

Here we would be discussing the ways to provide a seamless Internet experience to users accessing IPv4 Internet services through completely new “greenfield” IPv6-only networks. We would be even describing how to establish content providers as well as content enablers could transparently provide existing or new services to IPv6 Internet users by deploying Network Address Translation IPv6 to NAT64 IPv4 technology with little or no change in their existing network infrastructure, thus it would also maintain business continuity.

We know, that lots of things are to be discussed, which again wouldn’t be able to discuss in here, but worry not! You could have it all, by joining the Lab Prep Courses offered by the SPOTO.

Dual-Stack Network:

Dual stack is considered a transition technology in which IPv4 as well as IPv6 so as to operate in tandem over shared or dedicated links. In a dual-stack network, both IPv4, as well as IPv6, would be fully deployed across the infrastructure, so that configuration and routing protocols would be handled by both IPv4 and IPv6 addressing and adjacencies. Although dual-stack might appear to be an ideal solution, it would be presenting the two major deployment challenges to enterprises as well as ISPs:

•    It would be requiring a current network infrastructure that would be capable of deploying IPv6. In many cases, however, the current network might not be ready and might require hardware as well as software upgrades.

•    IPv6 would be needed to be activated on almost all the network elements. To meet this requirement, the existing network might need to be redesigned, posturing business continuity challenges.

Tunneling

Using the tunneling option, organizations would be able to build an overlay network that tunnels one protocol over the other by encapsulating IPv4 packets within IPv6 packets and IPv6 packets within IPv4 packets. The advantage of this approach is that the new protocol would be able to work without disturbing the old protocol, thus it would provide connectivity between users of the new protocol.

Tunneling again has the following two disadvantages:

● Users of the new architecture couldn’t use the services of the underlying infrastructure.

● Tunneling doesn’t enable users of the new protocol for communicating with users of the old protocol without dual-stack hosts, which again would negate interoperability.

Translation:

A translation which is also known as the Address Family Translation (AFT), would be facilitating the communication between IPv6-only as well as IPv4- only hosts and networks, whether in a transit, access or an edge network by performing IP header as well as address translation between the two address families.

 AFT isn’t a long-term support strategy; it would be considered as a medium-term coexistence strategy that could be used to facilitate a long-term program of IPv6 transition by both enterprises as well as ISPs.

The translation would be offering two major advantages:

● The translation would provide a gradual migration to IPv6 by providing seamless Internet experience to greenfield IPv6-only users, by accessing IPv4 Internet services.

● Existing, content enablers as well as content providers, would be able to provide services transparently to IPv6 Internet users by using the translation technology, with little or no change in the existing network infrastructure, thus you would be able to maintain IPv4 business continuity.

Thus, here we have gained certain information about the NAT64 Technology Connecting the IPv6 and IPv4 Networks. If you wish to have more info, you could gain it by joining the prep courses offered by the SPOTO.

Cisco Equipment Error Message Summary.

To successfully diagnose and troubleshoot network problems, network engineering technicians must master two basic skills. SPOTO will be committed to all kinds of equipment errors and high-edge IT technology. Now, SPOTO will introduce two basic skills.

The first is a clear understanding of network technologies and protocols. It is the basis for diagnosing and troubleshooting network problems. Without proper knowledge and experience, troubleshooting tools such as router diagnostic commands and network analyzers do not work.

The second skill that network engineering technicians must master is to apply the knowledge they have acquired in a structured way to diagnose and troubleshoot network problems. Although this article only describes some diagnostic commands, it should be emphasized that fault diagnosis and elimination is a structured approach. Many engineers and technicians believe that troubleshooting and troubleshooting programs are not as important as research and application technology itself. In fact, the right plan often plays a decisive role in troubleshooting and troubleshooting. During the troubleshooting process, an accidental behavior may resolve the fault, but it is not a substitute for structured troubleshooting and troubleshooting.

The elimination of network failures is a systematic project. It should be through defining problems, collecting facts, considering facts based on facts, establishing action plans, implementing plans, observing results and cyclic processes. This process is like the waterfall model of the software development process. Its importance is self-evident.

Error message format

The system error message format is as follows:

%Facility - sub-facility - Severity - Mnemonic: Message Text

Facility It indicates the name of the device involved in the error message. This value can be a protocol, a hardware device, or a system software module.

Subfacility It is only related to the Channel Interface Processor (CIP) card. Detailed information can be found in the relevant sections of the Cisco documentation.

Severity It is a number between 0 and 7. The smaller the value of the number, the higher the severity.

Mnemonic A single-valued code that uniquely identifies an error message. This code can usually imply the type of error.

Message Text This is a short description of the error message, including the router hardware and software information involved.

Below are examples of some error messages. Users can refer to the System Error Messages section of the CCO ISO documentation for a description of these error messages.

%DUAL-3-SIA: Route 171.155.148.192/26 stuck-in-active state in IP-EIGP 211. Cleaning up

%LANCE-3-OWNERR: Unit 0, buffer ownership error

It should be noted that not all messages involve a fault or problem condition. Some messages show information about status. For example, the following message only indicates that the ISDN BRI 0 interface is connected to a specific remote data.

%ISDN-6-CONNECT: Interface BRI0 is now connected to 95551212

Traceback Report

Some error messages related to router internal errors contain traceback information. When reporting an error to Cisco TAC, you should include this information in the error description.

Log of error messages and event information

Based on the importance and validity of the error message, Cisco error messages can be logged to the following locations:

& #61550; ;; console

& #61550; ;; virtual terminal

& #61550; ;; Syslog Server

& #61550; ;; internal buffer

The logging on command causes the output of the log message to go to the above location. For Syslog servers, the following global configuration commands must be used to indicate the server's IP address:

Logging IP-address

By using this command repeatedly, you can create a list of servers. When managing large networks, you usually need to set up a redundant server.

The logging buffered command is used to send log information to the internal buffer. The size of the buffer must be above 4096 bytes. The default values ​​vary depending on the system platform. The user needs to choose a buffer size that is appropriate for the environment. If the buffer is too small, the new message will overwrite the old one. This can cause problems. However, if the buffer size is too large, the system cache will be wasted. The no logging buffered command will prevent messages from being written to the internal cache.

Users can use the show logging command to display the contents of the internal buffer. If the user needs information for a certain period of time, first use NTP or manually set the clock. The specific operation is as follows:

YH-Router#clock set 11:37:00 December 2000

YH-Router#sh clock

11:37:03.596 PST Fri Dec 11, 2000

The timestamp and debug information for log messages can use the following global configuration commands:

YH-Router (config)#service timestamps log datetime

YH-Router (config)#service timestamps debug datetime

The terminal monitor command will display the log information during debugging on the current terminal. This command is not a configuration command. Instead, it can be used in command line mode when telneting to the router.

In most cases, users may need to display a certain level of log information. Therefore, the log information is divided into eight different levels, ranked according to the degree of importance from high to low:

& #61550; ;; Emergencies

& #61550; ;; Alerts

& #61550; ;; Critical

& #61550; ;; Errors

& #61550; ;; Warnings

& #61550; ;; Notifications

& #61550; ;; Informational

& #61550; ;; Debugging

For example, you need to display all log information on the console with a severity equal to or greater than Warning. You can use the following global configuration commands:

Logging console warning

Similarly, when sending some type of log information to the current terminal, use

Logging monitor level

Or use when sending information to the Syslog server

Logging trap level

Unlike the terminal monitor command, the logging monitor command is part of the router configuration. The former command does not allow execution at different security levels.

It should be noted that when logging logs to different locations, the system overhead varies greatly. The overhead of logging to the console is relatively large, but the overhead of logging to a virtual terminal is small. The overhead is smaller when using a Syslog server. The least expensive way to write logs is to write to the internal buffer.

Core Dump

In order to find out the cause of the router crash, we can use a lot of commands to get valid information. We have already explained the usage of the show stacks command. A core dump is a copy of the system memory image that can be written to a TFTP server. From this binary, we can get information about router crashes or serious misoperations, which can be used to rule out possible failures.

The following configuration command writes the core dump to the TFTP server corresponding to the IP address in the command:

Exception dump IP-address

The write core command is typically used to save a core image when a serious misoperation occurs on the router but does not completely crash.

Core dumps are only available for servers running IOS v 9.0 or higher. However, it is important to note that when using core dumps, it is best to get support from experienced engineers or Cisco TAC.

Where Can I Find The Best Online Course of CCIE RS Lab?

The CCIE R&S Lab exam is an eight-hour, hands-on exam which is going to require the candidates the skills for configuring and troubleshooting a series of complex networks to given specifications. Knowledge of troubleshooting is considered to be quite an important skill and candidates are estimated for diagnosing and solving issues as part of the CCIE R&S Lab exam.

Below mentioned are some details which you need to check out while selecting online courses for the CCIE R&S Lab Exam:

•    Seek An Experienced Teacher / Institute:

If you really need to excel at the certification exam, then it would be quite imperative to learn from the leaders as well as experienced professionals in this field. You are required to choose the right institute which would be providing ample guidance as well as lab training opportunities under the guidance of CCIE R&S certified professionals.

 •    Keep Your Self-Updated With Syllabus:

Be well versed with the Syllabus, follow the official CCIE R&S blogs for updates as well as practice workbooks since the stack is under constant revision. Also, keep in touch with the lab software as well as adhere to the same during your practice lab sessions.

 •    Be Well Versed With Networking Technologies as well as Topologies:

While the stack is in constant revising from time to time, you are required to to pay close attention to the topologies that are going to be asked in the exam, since sometimes the topologies are being repeated over a small duration of time, though knowing all the topologies at hand is also considered to be equally important. This would help you to ease out and improvise your chances.

 •    Get Rigorous Lab Training By Trained Professionals:

The candidates are required to go through the Rigorous Lab training is required under trained CCIE R&S Lab in a real lab infrastructure. You would have 8 hours of lab exam time to face, hence one must be fully familiar with the practical devices instead of going with the computer simulator programs. The more time you give to practice in the real-life lab infrastructure, the less stressed you might feel during your actual lab exam. Guidance under professional would be helping you overcome practical issues with tips.

 •    Time Management, Speed And Have Clear Concepts:

Cramming of stuff isn’t going to solve your problems. Hence it would be considered wise enough to keep your concepts crystal clear. This would help you out to even solve problems that you would have come across during practice with small changes. Lab exams are timed-based, the candidates are required to learn to manage your time as well as speed up with solving the problems since you would need to complete the exam within the allocated time. You would be needed to be really quick with solutions if you would wish to clear the exam in a single go.

 •    Mock Exams Before Lab Exam:

Taking a mock exam before your actual lab date is considered quite crucial for the candidates to ensure their success. This would help you out for practicing in the same stressful lab exam scenarios. And the more you are familiar with it, the less stressed you would be during your actual lab exam date. A number of virtual platforms are considered to be available to practice your exam from home or you could enroll in boot camps for the lab exam. Such practice of online test and simulator would quite help you gauge your knowledge of networking at hand.

 Well, there are many online training courses, which you could choose, but not all of them will lead you to success. I would recommend you to gain the courses offered by the SPOTO, they are considered amongst the best training provider across the globe.

Thoughts and Assessment of the CCIE R&S Lab Exam.

Dear students, I passed the CCIE  LAB exam to the RS track. Let me share my long and painful experience. So I finally did it, I hope this helps 1st and 2nd timers who want to attempt the lab. I am a college graduate who just graduated in 2019. I am also a student who just got into CCIE. In college, my major is completely unrelated to my computer, but I graduated and tried to do more, so I was in 2019. I came to the big family of SPOTO in March. Before that, I only knew that IT was a computer. It might be ridiculous to say it, but this is my idea when I first entered the IT industry. Before coming to the big family of SPOTO, it was like having a luxury train. I did a lot of courage because professional problems led to zero-based training. This was a big injury to me at the beginning. I started my long journey on the road of ignorance.

 NA is my first stop. My tutor is SPOTO 's teacher, because the university has not graduated yet, and it is a book that was read in Tianjin. Every Friday afternoon, I will rush to Tianjin from Tianjin, and I will finish the class on Sunday. I rushed back to Tianjin and ran back and forth between the two places. It was really busy at that time, but it was very fulfilling. It was during that time that I made a successful conclusion for my college career. From the initial IP address to the final OSPF, eigrp, rip and other network protocols, step by step, encountered a lot of problems in the middle, when Mr. Chen was our answering teacher, very responsible for helping me complete the software from Installing to the final experiment.

 NP is my second stop. My tutor at the time, its lectures were very good, but it was delayed for nearly two months because of the school's completion. In the two months, I spent a lot of time. Time to download the NP video, basically watching the video self-study, in fact, the NA video I saw at the beginning is the video recorded by SPOTO, but because the teacher's video recording time is too early, the NP stage has changed to a newer recorded video. This step by step through the stage of NA, NP. With the end of the NP phase, I also said goodbye to my college life.

 When I was just preparing to enter the IE stage, I became a promising learning stage. In the beginning, I successfully passed the CCIE written test. During that time, I was able to sleep and forget the SPOTO pen test question in the room. When I took the test, it was more than 300. The written test can also suggest that students use VCE software to carry out back and forth consolidation exercises. The tutorial can be searched on SPOTO's Youtube platform. The third stop is my IE stage. My tutor said in the first class: "Don't think that you are sitting in the IE classroom, you are a CCIE!" This sentence made me tighten the strings in the IE stage. Because the experiment was not completed on time, the old teacher was tempted by me, and eventually, I became the pistachio in the class. It also allowed me and the teacher not only to establish a teacher-student relationship but also to establish a friendly relationship. What needs to be emphasized here is that the experiments in IE are all classic experiments. The students have to practice and must master the principle so that they can fully prepare for the future LAB.

 The fourth stop is my LAB stage. In the preparation of the LAB stage, it can be said that it is the most exciting moment on the road. I was already preparing for the class in IE. I thought I would take CCIE very quickly, but at the beginning I took it. When I arrived at C1, I found that when the scattered knowledge was integrated into a network, the problem slowly came to the surface. The students with bad foundations should start to prepare for the jamming. In the process of version, there must be companions. Prepare together so that you can learn from each other and avoid boring. At that time, the teacher also gave me the direction of the version. From the time I got the version, the teacher suggested watching the version video first. There is a system in the brain, then I start to knock the code, and then I watch the video and take notes. I, the problem encountered in the process of knocking is also helped by the teacher of SPOTO. Later, as time went by, I completed the practice of two sets of C1 and C1+. If there is any good technique, it is the word “knock”. No matter when it is necessary to persevere. I don't want to say that when I first took C1, it took me five days to finish the first time. After repeated practice, I can reach 1 hour and 45 minutes at a time. So whether you are working or other factors, don't give up on knocking. If you don't knock for a while, you will find that you will always have some problems surrounding you. When I knocked out C1 and 1+ again, I put TS1 in the front. When TS1 started, it was knocking. After repeated knocking, I slowly understood it and later I could master it! Starting the C2 phase in LAB, I suggest that you can come to the site to see the video of Shen Huadi before knocking because, from C2, you can clearly feel that you have touched some strategic things, which has been described in detail in the teacher's recorded video. It will be very efficient to understand and then knock. Personally suggest that when C2 and C2+ are finished, you can intersperse the previous four sets of exercises, so that you can not only forget the previous one but also master the current one. On October 9th, the birth of C3 in China was ushered in. The original four sets of versions have already been overwhelmed by people. In any case, sooner or later, they will face each other and fight side by side with SPOTO. In the end, C3 was knocked down smoothly, and it reached the level of proficiency. The fastest time was 1 hour and 46 minutes. Finally in May 2019 Pass final CCIE!

 In general, you can make a perfect match, only to be able to master the version to the extreme, so that you can qualify for a series of problems in the examination room. Personally, I didn't get used to scripting habits, and all the commands were also hand-picked during the exam. If you are the same classmate as me, I suggest you not to develop the habit of scripting, because the excessive process takes time. The mentality of the exam is also very important. When you are in a normal state, don't panic. The young people of our generation are mostly arrogant, the test pressure is changing, and the courage goes forward. This CCIE journey has made me grow a lot. In the preparation stage of the edition, some teachers took me to change a set of TS1; there are many small partners who are knocking on the version every day; they have a careful interpretation of the teachers when they encounter difficulties; they also have the care of the teachers a few days before the test. Uh... I sincerely thank all the teachers of SPOTO for their hard work and thanks to the companions who have helped me. Thank you! I also hope that SPOTO will become more and more prosperous, and cultivate more IT network talents, and the bigger! This IT trip is a trip to me without a destination. Every stop is the most exciting moment in my life. Now I have been in a hurry for 9 months. I met many comrades here and I know a lot. Friends, when they give up, they often warn themselves: "Since others can persist, why can't they say it?" I also sent this sentence to the comrades behind me. As long as I persist, I will pass the exam smoothly. Come on, companion. CCIE RS is just the beginning for me. No matter whether this road is wrong or not, since you choose, you don't have to look back and hope that you will be bright in the future. Good luck in all of your studies!
