3 Once OSPF or OSPFv3 is registered with BFD at the protocol level, enable the OSPF or OSPFv3
interface(s) that participate in BFD using the ip ospf interface bfd-state or the ipv6 ospf interface bfd-
state command. For example:
-> ip ospf interface vlan-10 bfd-state enable
-> ipv6 ospf interface vlan-2071 bfd-state enable
The above command enables BFD on the interfaces named vlan-10 and vlan-20. To enable BFD on all
configured OSPF or OSPFv3 interfaces, use the ip ospf bfd-state all-interfaces or the ipv6 ospf bfd-state
all-interfaces command. For example:
-> ip ospf bfd-state all-interfaces enable
-> ipv6 ospf bfd-state all-interfaces enable
To disable BFD for all configured OSPF or OSPFv3 interfaces, use the ip ospf bfd-state all-interfaces or
the ipv6 ospf bfd-state all-interfaces command with the disable keyword. For example:
-> ip ospf bfd-state all-interfaces disable
-> ipv6 ospf bfd-state all-interfaces disable
4 To display the BFD status on an OSPF or OSPFv3 interface, use the show ip ospf interface or the
show ipv6 ospf interface command. For example:
-> show ip ospf interface
