Hi

You can use:

show ip bgp summary

show ip bgp neighbor

show ip bgp; will show you the local router-id.

Hope it is useful

thank you for the reply.
i mean without getting into remote router, how do i know what IP address "neighbor x.x.x.x" remote router is using for BGP peering session?

Hi

Unfortunately there is no such command directly but it can be found through show ip bgp neighbor, you could execute a debug or use wireshark. Other way is to see the neighbor IP and see the matching with the local networks like point to point networks or if you are using loopbacks you can see the associated local IP displayed on the command: neighbor x.x.x.x update-source <interface>

Hello

Along with the otherssuggestions

Bgp  will peer on the address specifed in the BGP routing stanza so you can take it from there or use pipeon the sh ip bgp neighbors commnad

sh ip bgp neighbors | in Local|Foreign
