Congure BFD for OSPF
When you use BFD with OSPF, the OSPF protocol registers with the BFD manager. BFD sessions are established with all neighboring
interfaces participating in OSPF. If a neighboring interface fails, the BFD agent noties the BFD manager, which in turn noties the OSPF
protocol that a link state change has occurred.
Conguring BFD for OSPF is a two-step process:
1 Enable BFD globally.
2 Establish sessions with OSPF neighbors.
