Information
Protocol Liveness is a feature that notifies the BFD Manager when a client protocol
(e.g OSPF, 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.
