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

role {active | passive}]
To disable BFD for all neighbors configured through static routes, use the no ip
route bfd [interval interval min_rx min_rx multiplier value role
{active | passive}] command.
