Configuring BFD for OSPF is a two-step process:
1. Enabling BFD
2. Establishing sessions with OSPF

Establishing sessions with OSPF neighbors
BFD sessions can be established with all OSPF neighbors at once or sessions can be established with all
neighbors out of a specific interface. Sessions are only established when the OSPF adjacency is in the full
state.
