Configuring Crlsp Backup; Configuring Mpls Te Frr; Enabling Frr - HP MSR2000 Configuration Manual

Step
3. Configure an associated
bidirectional MPLS TE tunnel.

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
1. Enter system view.
2. Enter MPLS TE tunnel interface
view.
3. Enable CRLSP backup and
specify the backup mode.
4. Specify a path for the primary
CRLSP and set the preference
of the path.
5. Specify a path for the backup
CRLSP and set the preference
of the path.

Configuring MPLS TE FRR

MPLS TE FRR provides temporary link or node protection on a CRLSP. When you configure FRR, note the
following restrictions and guidelines:
Do not configure both FRR and RSVP authentication on the same interface.
•
Only MPLS TE tunnels established through RSVP-TE support FRR.
•

Enabling FRR

Perform this task on the ingress node of a primary CRLSP.
To enable FRR:
Step
1. Enter system view.
2. Enter tunnel interface view of
the primary CRLSP.

Remarks
By default, no bidirectional tunnel
is configured, and tunnels
established on the tunnel interface
are unidirectional MPLS TE tunnels.

N/A
By default, tunnel backup is
disabled.
By default, MPLS TE uses the
dynamically calculated path to set
up the primary CRLSP.
By default, MPLS TE uses the
