201BCRLSP backup configuration example
415BNetwork requirements
Switch A, Switch B, Switch C, and Switch D run IS-IS and IS-IS TE.
Use RSVP-TE to establish an MPLS TE tunnel from Switch A to Switch C to transmit data between
the two IP networks. 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.
