Basic BGP configurations: IBGP and EBGP

BGPThe basic configuration process is as follows:

Run IBGP between RouterB and RouterB, and run EBGP between Router B and Router C.

Router

Router B

Router C

 

Note: Most configurations must be non-synchronous. You must configure the BGP Route to be synchronized only when it is necessary to introduce the BGP Route into IGP. This example only demonstrates how to configure IBGP and EBGP. In the actual network, as long as there is a TCP connection between the routers, you can establish a BGP neighbor relationship, that is, you can establish a BGP neighbor relationship as long as you can ping. the difference between IBGP and EBGP is that the neighbor's AS number is different.

BGP is a routing protocol that dynamically exchanges routing information between autonomous systems. Through the above configuration instance, I hope you will have a deep understanding of BGP.
