Usage Information When you enable fall-over, BGP keeps track of IP or IPv6 reachability to 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 peer IP or
IPv6 destination/local address), BGP brings down the session with the peer.
