Command Modes ROUTER BGP
Command History
Version 8.2.1.0 Introduced on the E-Series ExaScale.
Version 7.4.1.0 Introduced
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.
