Setting a DSCP value for outgoing RSVP packets

The DSCP value of an IP packet specifies the priority level of the packet and affects the transmission
priority of the packet.
To set a DSCP value for outgoing RSVP packets:
Step
1. Enter system view.
2. Enter RSVP view.
3. Set a DSCP value for outgoing
RSVP packets.

Configuring RSVP GR

RSVP GR depends on the RSVP hello extension feature. 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.
