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

5 Once OSPF is registered with BFD at the protocol level and BFD is enabled on the desired OSPF inter-
face(s), use the show ip bfd interfaces command to display BFD-enabled interfaces. For example:
-> show ip bfd interfaces
