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:

1. Enter system view.
system-view N/A
2. Enter interface view.
