BGPIt is a path vector protocol that constructs an Overview map based on autonomous systems for each destination. NLRI = Network Layer Reachability Information, Network Layer accessibility Information. BGP uses the AS_PATH attribute to detect loops. If the AS_PATH contains its own AS number, the prefix is rejected. Specifically, this is for eBGP. Because iBGP does not check AS_PATH! In addition, iBGP does not change the AS_PATH attribute.
So how does
Border Gateway Protocol (BGP) is an Internet routing Protocol. BGP itself is not too complex, but those first involved in this field may be unfamiliar with this concept hidden behind Autonomous System routing. We hope that you can use this article to briefly understand the working principle of BGP and the problems it produces and can solve.

External Gateway Protocol: BGP (Border Gateway Protocol)
BGP: the protocol for exchanging route information between as routers of different self-made systems.
The Internal Gateway Protocol rip or OSPF is used to send a datagram to the target site from the source site as much as possible in an. However, the external gateway protocol uses different BGP environments
At present, there are also a lot of BGP routing protocol applications, so I have studied the synchronization problem in the BGP routing protocol. Here I will share it with you and hope it will be useful to you. BGP protocol: A router running the BGP protocol will not advertise the routing information learned from the i
