One 、BGP brief introduction ：

• Border gateway protocol （BGP） Is running on  TCP  A kind of Autonomous systems Of Routing protocol . BGP Is the only one that deals with The Internet Protocol for large and small networks , It is also the only way to properly handle the irrelevant Routing domain A protocol for multiple connections between . BGP Builds on the EGP On the experience of . BGP The main function of the system is with other BGP System exchange network reachable information . Network accessibility information includes listed autonomous systems （AS） Information about . This information effectively constructs AS The topology of the interconnection and thus the Routing loops , At the same time AS Strategic decisions can be implemented at a level .
