CRLSP backup configuration example

Network requirements
Router A, Router B, Router C, and Router D run IS-IS and IS-IS TE.
Use RSVP-TE to establish an MPLS TE tunnel from Router A to Router 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.
