3. Configure an associated

bidirectional MPLS TE tunnel.

By default, no bidirectional tunnel

is configured, and tunnels

established on the tunnel interface

are unidirectional MPLS TE tunnels.

Configuring CRLSP backup

CRLSP backup provides end-to-end CRLSP protection. Only MPLS TE tunnels established through RSVP-TE

support CRLSP backup.

Perform this task on the ingress node of an MPLS TE tunnel.

To configure CRLSP backup:
