The new Cisco EI CCIE enterprise infrastructure has been released for 2 years, and RS routing switching has officially withdrawn from the stage of history. Whether the new EI CCIE is the same as the RS has become a concern for network workers.

The CCIE RS routing exchange certification, which has been popular in the world for more than 20 years, is the most familiar direction of CCIE certification. EI CCIE, a new certification for global networkers, is paying attention. We analyze their differences from the content of the knowledge system.

The content of the RS course is mainly based on the routing and switching of traditional enterprise network architecture, with routing accounting for 50% and switching Parts account for 30%, and other feature points account for 20%. The main focus is on the routing part. EIGRP, OSPF, and BGP are compulsory content in the exam. The second-layer basic switching part and the third-layer redundant switching part are also compulsory content. In addition, there are some security, VPN, QOS, multicast and other technologies as features that occupy about 20% of the content.

The course content of EI is also mainly based on enterprise network architecture. The difference is that it is a new type of enterprise network architecture, adding soft-defined SDN technology, and soft-defined SDN technology accounts for 25% of the exam. test point. In the modification of the routing part, EIGRP does not focus on learning, and only requires the learning of this routing protocol by "understanding EIGRP". In addition, OSPF and BGP are still required to be studied. According to EI's standard teaching requirements, we originally focused on the CCNP course in the RS theoretical course, but now EI's CCNP only requires 5 full-days to complete. This also shows that Cisco believes that after 20 years of RS technology promotion , CCNP popularity has been very mature. It is no longer necessary to spend too much time studying it, and more time should be devoted to learning new technologies of SDN.

In the detailed comparison of the two directions of cancellation and addition, it can be seen that about 50% of the original knowledge system of RS has been retained in the existing knowledge system of EI, and the new content includes: 25% soft-defined SDN technology, 15% security and features, 10% programming and other technologies.

It is not difficult to see through the knowledge system analysis of EI CCIE enterprise network architecture foundation, EI architecture is the beginning of the digital transformation of enterprise network, and automation and intelligence are ultimately the development direction of EI CCIE assessment. In the soft-defined network, the requirements for the basic network architecture are getting simpler and simpler. However, this does not mean that network workers should transform into programming. Even for the policy formulation of the soft-defined network, the architecture design must have very powerful network technology. for support. Therefore, what we need to recognize is the future of the EI direction, and it also indicates that we should be well prepared in the transformation stage of enterprise network architecture design.
