3. Configure an associated
bidirectional MPLS TE tunnel.
mpls te bidirectional associated
reverse-lsp { lsp-name lsp-name |
lsr-id ingress-lsr-id tunnel-id
tunnel-id } }
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:

Remarks
1. Enter system view.

2. Enter MPLS TE tunnel interface
view.

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 } [ no-cspf ]
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 } [ no-cspf ]
By default, MPLS TE uses the
dynamically calculated path to set
up the backup CRLSP.
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:
