The range is 50 to 1000. The default is 200.min_rxmillisecondsEnter the keyword min_rx to specify the minimum rate at whichthe local system would like to receive control packets from theremote system. The range is 50 to 1000. The default is 200.multiplier Enter the keyword multiplier to specify the number ofpackets that must be missed in order to declare a session down.The range is 3 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 fromthe active system.The default is Active.Defaults See Parameters.Command Modes INTERFACEBidirectional Forwarding Detection (BFD) 409
