Implementation Of Routing Information Protocol On Linux

Internet is a product in the information times. It has stretched to every corner of the world during these years. The distance between people are becoming smaller and peoples can not live without it. There is a saying that, the Internet is another milestone in human-being's history.In the future, the network will keep growing, and the networking engineers will also make it more powerful. But, there is a problem about the costs when we update the bandwidth and enhance the capacity of the network, which is often overlooked by us. High-performance routing and switching equipments in the core layer are irreplaceable, but in access layer, can we get a method to save the costs? The answer is yes.This thesis uses personal computer as low-performance router to handle the problem, which can entry the users in access layer into the Internet. It uses a low-performance personal computer with Linux operating system working as a router. The configuration level of Linux PC is not very high and there are many Chinese versions of Linux, and also Linux will not be influenced by the virus in Windows. Besides this, the software named Zebra using in the system is a open-sourced one, which is provided by GNU. It' s free and it is a good method. The computer will be used effectively, and the costs of constructing a network will be less then before. There is no need to buy a router for the edging users.On the basis of previous research, this thesis gives an integrated routing project with the help of RFC 2453 and Zebra which is open-sourced. The platform of the experiment is Redhat-Linux (the core version is 2.4.20 or 2.4.18). This thesis begins with the contrast of Routers and Personal Computers. The first chapter simply introduces the recent network, the concept of routers and the soft-routing. The second chapter gives a detailed introduction of RIP described in RFC 2453. The third chapter deeply analyzes the codes of RIP in Zebra and gets a new command to lead future development. In the fourth chapter, there are some cases about Linux PC and Cisco routers working together. The last chapter gives a summarization and some future works for the RIP routing.
