[Abstract]:Up to now, the transmission based on IP is still the most mature and reliable technology. Routing and switching are the most basic part of data transmission, and efficient and stable routing protocol is an important factor to ensure the performance of trusted routers. With the rapid development of information technology and the continuous expansion of network size, more and more packets need to be processed by routers, which undoubtedly has a great impact on the performance of routers. In order to meet the requirements of router performance, modern network technology extends ISIS routing protocol. On the basis of deep understanding of ISIS protocol and related technical documents, using RFC5120 [1] as the standard and adopting agile development method, this paper designs and implements the function of ISIS supporting multi-topology routing. The main work of this paper includes: the requirement analysis and modeling of the system, the overall design and module partition based on the existing ISIS protocol, and the realization of dividing the IPv4 and IPv6 topology to solve the problem of routing black hole; The global topology is artificially divided into several different sub-topologies, and each sub-topology is routed separately to realize the forwarding function of different traffic flows within the corresponding topology in IPv4 unicast networks. Finally, the basic function verification and performance test are carried out on the H3C router. The test results based on H3C router show that ISIS supports multi-topology routing correctly, and the system runs stably, and achieves the design goal of the project.
