Networks not directly connected are not considered valid for best path selection. Command History Version 7.8.1.0 Version 7.7.1.0 Introduced support on S-Series Introduced support on C-Series neighbor fall-over e c s Enable or disable fast fall-over for BGP neighbors. Syntax neighbor {ipv4-address | peer-group-name} fall-over To disable, use the no neighbor {ipv4-address | peer-group-name} fall-over command. Parameters ipv4-address peer-group-name Enter the IP address of the neighbor in dotted decimal format. Enter the name of the peer group. Defaults Disabled Command Modes ROUTER BGP Usage Information When fall-over is enabled, BGP keeps track of IP or IPv6 reachability to the peer remote address and the peer local address. Whenever either address becomes unreachable (i.e, no active route exists in the routing table for peer IP or IPv6 destination/local address), BGP brings down the session with the peer.
