Displaying Information about the Routes from a Peer

To display information about each route learned from a specific peer, use the new peer parameter in the command:

show bgp route[=prefix] [peer=ip-address] [other optional parameters]

The peer parameter specifies the IP address of the peer. If you specify a peer, the router or switch only displays routes that it learned from that peer. If you specify the router or switch’s router ID, it displays all locally originated routes. The peer parameter has no default.

Note that this enhancement did not change any fields in the output of the show bgp route command; it simply provides another method of filtering the displayed routes.
