3 Once OSPF is registered with BFD at the protocol level, enable the OSPF interface(s) that will partici-
pate in BFD using the ip ospf interface bfd-std 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 ip ospf bfd-std all-interfaces command. For example:
-> ip ospf bfd-std all-interfaces
To disable BFD for all configured OSPF interfaces, use the no form of the ip ospf bfd-std all-interfaces
command. For example:
-> no ip ospf bfd-std all-interfaces
4 To display the BFD status on an OSPF interface, use the show ip ospf interface command.
For example:
-> show ip ospf interface
Interface DR Backup DR Admin Oper BFD
Name Address Address Status Status State Status
----------+-------------+--------------+---------+---------+----------+---------
vlan-10 213.10.10.1 213.10.10.254 enabled up DR enabled
vlan-20 215.10.10.254 215.10.10.1 enabled up BDR disabled
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-std interfaces command to display BFD-enabled interfaces. For example:
->show ip bfd-std interfaces

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