Step Command Remarks
bidirectional MPLS TE tunnel
and specify the local end as
the passive end of the tunnel.
passive
reverse-lsp ls
-id

disabled on the tunnel interface,
and tunnels established on the
tunnel interface are unidirectional
MPLS TE tunnels.
To configure an associated bidirectional MPLS TE tunnel:
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. 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, bidirectional tunnel is
disabled on the tunnel interface,
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:
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 tunnel 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,
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.
