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. bfd enable CONFIGURATION Mode 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.
