Usage
Information
Protocol Liveness is a feature that notifies the BFD Manager when a client protocol (for example, OSPF
and ISIS) is disabled. When a client is disabled, all BFD sessions for that protocol are torn down.
Neighbors on the remote system receive an Admin Down control packet and are placed in the Down state.
Peer routers might take corrective action by choosing alternative paths for the routes that originally
pointed to this router.
ip route bfd
Enable BFD for all neighbors configured through static routes.
Syntax
ip route bfd [prefix-list prefix-list-name] [interval interval min_rx
min_rx multiplier value role {active | passive}]
