Configure Bfd For Is-Is - Dell S3048-ON Configuration Manual

Configure 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 notifies the BFD manager, which
in turn notifies the IS-IS protocol that a link state change occurred.
Configuring BFD for IS-IS is a two-step process:
1 Enable BFD globally.
2 Establish sessions for all or particular IS-IS neighbors.
