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. clear bfd counters Clear all BFD counters, or counters for a particular interface.
