Usage Information Protocol Liveness is a feature that noties 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.
