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:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter MPLS TE tunnel interface view. | interface tunnel tunnel-number [ mode mpls-te ] | N/A |
3. Enable CRLSP backup and specify the backup mode. | mpls te backup { hot-standby | ordinary } | By default, tunnel backup is disabled. |
4. Specify a path for the primary CRLSP and set the preference of the path. | mpls te path preference value { dynamic | explicit-path path-name } | By default, MPLS TE uses the dynamically calculated path to set up the primary CRLSP. |
5. Specify a path for the backup CRLSP and set the preference of the path. | mpls te backup-path preference value { dynamic | explicit-path path-name } | By default, MPLS TE uses the dynamically calculated path to set up the backup CRLSP. |
