Usage Information 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.
Related Commands
• show ip bgp neighbors — display information on the BGP neighbors.

To accept external routes from neighbors with a local AS number in the AS number path, congure Internal BGP (IBGP) routers.
Syntax
