Usage Guidelines

Usage Scenario

If a tunnel fails, RSVP sends PathError and ResvTear messages carrying reasons for a tunnel going Down to the ingress. The reasons are as follows:

CSPF fails to search for a reachable route.
The node fails to reserve bandwidth.
Labels conflict.
Messages sent by a peer are dropped.
Updating signaling packets times out.
RSVP GR fails.
Tunnel preemption is performed.
An incorrect operation is performed.
To enable a transit node or the egress to send an RSVP message not carrying reasons for a tunnel going Down, run the mpls rsvp-te send-message down-reason disable command.

Prerequisites

MPLS RSVP-TE has been enabled globally using the mpls rsvp-te command.
