Introduced Usage Information Related Commands When you enable failover, BGP keeps track of IP or IPv6 ability to reach the peer remote address and the peer local address. Whenever either address becomes unreachable (for example, no active route exists in the routing table for the peer IP or IPv6 destination/local address), BGP brings down the session with the peer. show ip bgp neighbors - displays information on the BGP neighbors. 368 Border Gateway Protocol
