3 Once OSPF is registered with BFD at the protocol level, enable the OSPF interface(s) that will partici-
pate in BFD using the
pate in BFD using the
command. For example:
-> ip ospf interface vlan-10 bfd-std enable
The above command enables BFD on the interface named vlan-10. To enable BFD on all configured
OSPF interfaces, use the
OSPF interfaces, use the
-> ip ospf bfd-std all-interfaces
To disable BFD for all configured OSPF interfaces, use the no form of the
command. For example:
-> no ip ospf bfd-std all-interfaces
4 To display the BFD status on an OSPF interface, use the
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

6 To establish BFD sessions with neighbors that are in full state only, enter the
command as shown below:
-> ip ospf interface int1 bfd-std drs-only
