Step Command
Remarks
2.
Enter MPLS TE tunnel interface
view.
interface tunnel tunnel-number
[ mode mpls-te ]
N/A
3.
Configure a co-routed
bidirectional MPLS TE tunnel
and specify the local end as
the active end of the tunnel.
mpls te bidirectional co-routed
active
By default, no bidirectional tunnel
is configured, and tunnels
established on the tunnel interface
are unidirectional MPLS TE tunnels.
To configure the passive end of a co-routed 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 a co-routed
bidirectional MPLS TE tunnel
and specify the local end as
the passive end of the tunnel.
mpls te bidirectional co-routed
passive reverse-lsp 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.
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, 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:
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 CRLSP backup and
specify the backup mode.
mpls te backup { hot-standby |
ordinary }
By default, tunnel backup is
disabled.
