Usage Information Protocol Liveness is a feature that noties 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.
