I have been engaged in data communication professional work for 5 years since I worked. Because of the working relationship, the technologies and models I contacted are quite extensive, from the basic network to the IP network, from the new bridge DDN, Nortel ATM, Juniper/Redback BRAS.
I was so happy to pass the CCIE Lab exam with the help of SPOTO' professionals and tutor. because they can give me some valuable suggestion.
RoutersfromCisco/Juniper/Huawei/Alcatel and other manufacturers are considered to be old friends. I used to be familiar with Juniper and Huawei equipment, so it is no stranger to contact Cisco. Since 2018, I gradually came into contact with Cisco products. I feel that the certification system of cisco is very good. I just looked at the PPT from CCNA and CCNP, and then I saw the English version of Routing TCP/IP Volume 1 Volume 2, Cisco.com. Documentation and so on. I have attended the SPOTO training course, including the CCIE written test. What I am saying is that SPOTO's learning materials are really useful and cover most of the questions.
To participate in the CCIE certification exam, on the one hand, to test the academic performance of the past few years, on the other hand, I am actually a little lazy and not enthusiastic about learning, girls, of course, prefer shopping, try new cosmetics, beautiful clothes, too I often linger on Taobao, indulge in the road, and spend money on exams to pressurize myself. From the CCIE written test last year, and now through CCIE LAB, recalling this nearly one year of preparation experience, it can be said that it is really hard. Especially when I am preparing for the exam like me, I have to go to work normally during the day, and I have to do my own job. Although I work at the ISP, some things can be learned immediately after I understand it, but most of the work is still repeated daily maintenance or copywriting. Processing can only be taken to study and experiment, stay up late at night, and go to work the next day, which makes me like coffee.
In terms of learning content, it is recommended to strengthen the learning of the TCP/IP protocol. This is very important and is the foundation. If it is just a command to get cooked, then it is just a skilled worker. When the foundation is laid, you can bypass the class. Recommend everyone to see the TCP/IP detailed volume 1 protocol. This is not Jeff Doyle's Routing TCP/IP. This country has 3 volumes of Chinese translation, Volume 1 protocol, Volume 2 implementation, and Volume 3 transactions. To prepare for the CCIE exam, you only need to look at Volume 1. In addition, the Sniffer tool is a good assistant for learning protocols.
Do more experiments, be sure to do more experiments. I have not participated in the training course or purchased the remote machine. I did the experiment through the SPOTO rack. I work at the ISP. The Catalyst 3550 switch is not lacking, and there are many routers, but only GSR12000, 6509, and Only POS, GE port. So I bought a few 25/26 myself, managed by a terminal server, completely a standard rack. For the rack, according to the equipment and ios list published on the Cisco website, you need 2 Catalyst 3550, 62621 or 3640, 3 Backbone, and 1 Terminal server. My own rack is 2 Catalyst 3550, 2 2600, 4 2500, and another 2511 is the Terminal server, 1 4500 is the Backbone, and 1 is the 7500 FR Switch. The most economical solution can be a RAC Switch with 1 Catalyst 2950, 6 2500, 1 4T or 8T 4500 (connected with 2 2501s, can also be a 4 serial port FR Switch, or even a dedicated router Do FR Switch, the serial port of 2 routers can also encap fr, but the configuration feels different.) I have passed the written test last year, and I have been participating in LAB for nearly a year this year. I have been doing experiments. The LAB exam blueprint published by SPOTO is very detailed. The scope of the test will not exceed this. I will follow this outline. In the section of the experiment, in fact, a lot of knowledge points usually work a lot, there are some features of what is not commonly used (Vivy has worked for 5 years, but in normal work, actually do MPLS / × × ×, VPDN, PPPOE, and other aspects are more). An operationally manageable network should be more uniform and stable as possible. It is impossible to have a complicated routing environment. The operator's network will not encounter routing two-way re-release. The advice that needs to be given to everyone is that the main purpose of the experiment is to master the knowledge points through the process of experimenting, to encounter problems that do not understand, to check the documents, and then to show and debug. The purpose of the experiment is definitely not to recite the commands. Many orders I remember. living. Of course, there are some errors in the Cisco documentation online, and I found several places. For example, in RIP, documentation says that the split horizon is turned off, the summary route can be advertised, etc., and the access list in the helper address on two routers converts from broadcast to multicast: access-list 135 permit any udp 4000, access- List 135 deny any UDP, maybe a clerical error.
Recommended SPOTO, is the leader of IT certification company, there are many experts here, often answer questions enthusiastically, the answer is very accurate and professional, much better than the domestic ccie forum, of course, English, good friends can go. For example, I know from here that the monitor session needs a lot of knowledge about the reflected port.
In addition, I would like to give you some advice. CCIE's annual salary of 300K, Title can earn a lot of money, get CCIE certification, you can get a high salary. The era has passed. Now many paper ccie can't find a job with a monthly salary of 3K. The graduated schoolmate went to the training to test ccie. I think it is the correct choice. The entire training plus exam can be taken with little money. The network of the actual operation and the network of the laboratory are completely different. Of course, the laboratory can achieve certain miniaturization and re-emergence of the macro network, but the complex application environment and traffic model in the commercial network, and accumulated in the engineering practice. The work experience, the concept of a global network built up, the overall planning and understanding of the network, not only a few months in the lab can be obtained by closing the door. It is recommended that you still accumulate some work experience, not necessarily looking for a big company to work, small companies often give you more opportunities, with a few years of work experience, at that time if you think your work and ccie have a relationship, ccie or It is very necessary, and it will be better to go to the exam, and the chances of passing will be much greater.
Passing the CCIE exam is not the end, but a new starting point. After you really work, you will find that Cisco is only a pioneer in the internet field. Now there are many up-and-coming talents who are struggling to catch up. There are various kinds in the entire communication market. Such technologies as DDN, ATM, xDSL, BRAS, SDH, DWDM, ASON, MSTP, NGN, etc., also have many broader fields in the entire data communication field, such as Security, VOIP, MPLS, XX, NGI, etc. Let's explore.
Finally, thank my friends who gave me selfless help, thank my parents, thank my friend Frank, thank Vincent, thank Scott Morris (CCIE4 #4713), thank Cisco Connection Online, thank SPOTO, thank my puppy-- She has been with me forever.
Equipment and IOS version of the CCIE Lab Exam:
The IOS version I tested was 12.3 and 12.2. By November 13, 2006, I had to change the new device and the new version of IOS. Below is a list of devices and IOS versions for the CCIE LAB exam, including now and after November 13, 2006. During the exam, you may see a new IOS than the list below but will not test the updated Features.
