CRLSP backup configuration example

Network requirements

Switch A, Switch B, Switch C, and Switch D run IS-IS.
Use RSVP-TE to establish an MPLS TE tunnel from Switch A to Switch C. Enable CRLSP hot backup for the

tunnel to simultaneously establish a primary CRLSP and a backup CRLSP. When the primary CRLSP fails,
traffic is switched to the backup CRLSP.
