Therange is 50 to 1000. The default is 100.min_rxmillisecondsEnter the keyword min_rx to specify the minimum rate at which thelocal system would like to receive control packets from the remotesystem. The range is 50 to 1000. The default is 100.multiplier Enter the keyword multiplier to specify the number of packetsthat must be missed in order to declare a session down. The range is3 to 50. The default is 3.role [active |passive]Enter the role that the local system assumes:• Active—The active system initiates the BFD session. Bothsystems can be active for the same session.• Passive—The passive system does not initiate a session. Itonly responds to a request for session initialization from theactive system.The default is Active.Defaults See Parameters.Command Modes INTERFACE327
