Step
2. Enter RSVP view.

RSVP packets.

Configuring RSVP GR

RSVP GR depends on the RSVP hello extension function. When configuring RSVP GR, you must
enable RSVP hello extension.
Perform this task on GR-capable devices.
To configure RSVP GR:
Step
1. Enter system view.
2. Enter RSVP view.
3. Enable GR for RSVP.
4. Return to system view.
5. Enter interface view.
6. Enable RSVP hello
extension.

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
1. Enter system view.
2. Enter interface view.
3. Enable BFD for the RSVP
neighbor on the interface.
