3. Configure a co-routed
bidirectional MPLS TE tunnel
and specify the local end as
the passive end of the tunnel.

By default, no bidirectional tunnel
is configured,
and tunnels
established on the tunnel
interface are unidirectional MPLS
TE tunnels.
To 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:
1. Enter system view.

N/A
2.
interface view.

N/A
3. Enable CRLSP backup and
specify the backup mode.
mpls te backup
{
hot-standby
|
}
By default, tunnel backup is
disabled.
4. Specify a path for the primary
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
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.
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.
