Enabling BFD for RSVP
If a link fails, MPLS TE tunnels over the link fail to forward packets. MPLS TE cannot quickly detect a link failure. To address this issue, you can enable BFD for RSVP so MPLS TE can quickly switch data from the primary path to the backup path upon a link failure.
To enable BFD for RSVP:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | interface interface-type interface-number | You must enable RSVP on the interface. |
3. Enable BFD for the RSVP neighbor on the interface. | rsvp bfd enable | By default, RSVP BFD is disabled. |
