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.
