Congure BFD for IS-IS
When using BFD with IS-IS, the IS-IS protocol registers with the BFD manager on the RPM. BFD sessions are then established with
all neighboring interfaces participating in IS-IS. If a neighboring interface fails, the BFD agent on the line card noties the BFD
manager, which in turn noties the IS-IS protocol that a link state change occurred.
Conguring BFD for IS-IS is a two-step process:
1. Enable BFD globally.
2. Establish sessions for all or particular IS-IS neighbors.
