Enables Bidirectional Forwarding Detection (BFD) on a specific OSPFv2 interface.
Interface subtype configuration mode
BFD sessions are initiated only if BFD is also enabled globally using the bfd command in OSPF router configuration mode. If BFD is disabled using the no bfd command in OSPF router configuration mode, BFD sessions on specific OSPFv2 interfaces are deregistered.
The no form of the command removes all BFD sessions from a specified interface.
The following example enables BFD on an OSPF Ethernet interface.
device# configure terminal device(config)# interface ethernet 1/4 device(conf-if-eth-1/4)# ip ospf bfd
The following example disables BFD on an OSPF virtual Ethernet (VE) interface.
device# configure terminal device(config)# interface ve 24 device(config-if-ve-24)# no ip ospf bfd
