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 [interval
interval

To disable BFD for all neighbors configured through static routes, use the
no ip
