BFD for OSPF
You can configure BFD to monitor and notify reachability status between OSPF neighbors. When you use BFD with OSPF, BFD
sessions are established between all neighboring interfaces participating with OSPF full state. If a neighboring interface fails,
BFD notifies OSPF protocol that a link state change has occurred.
To configure BFD for OSPF:
1. Enable BFD Globally.
2. Configure OSPF on the interconnecting routers. For more information, see Open Shortest Path First (OSPFv2 and OSPFv3).
Enable BFD Globally
To enable BFD globally:
Enable BFD globally.

Establishing BFD sessions with OSPFv2 neighbors
You can establish BFD sessions with all OSPF neighbors at one go. Alternatively, you can also establish BFD sessions with OSPF
neighbors corresponding to a single OSPF interface.
To establish BFD sessions with OSPFv2 neighbors:
1. Enable BFD globally
bfd enable
