3.
Enable CRLSP backup and
specify the backup mode.
mpls te backup

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
{

}
[

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
{

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,
follow these 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:

By default, FRR is disabled.
If you specify the

must have bandwidth protection.
Configuring a bypass tunnel on the PLR
Overview
To configure FRR, you must configure bypass tunnels for primary CRLSPs on the PLR by using the
following methods:
•
Manually configuring a bypass tunnel on the PLR
—Create an MPLS TE tunnel on the PLR,
and configure the tunnel as a bypass tunnel for a primary CRLSP. You need to specify the
bandwidth and CT that the bypass tunnel can protect, and bind the bypass tunnel to the egress
interface of the primary CRLSP.
You can configure a maximum of three bypass tunnels for a primary CRLSP.
•
Configuring the PLR to set up bypass tunnels automatically
—Configure the automatic
bypass tunnel setup function (also referred to as the auto FRR function) on the PLR. The PLR
automatically sets up two bypass tunnels for each of its primary CRLSPs: one in link protection
