•
For a co-routed bidirectional tunnel, configure one end of the tunnel as the active end and the other
end as the passive end, and specify the reverse CR-LSP at the passive end.
•
For an associated bidirectional tunnel, specify a reverse CR-LSP at both ends of the tunnel.
To configure the active 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 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:

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

Configure an associated
bidirectional MPLS TE tunnel.

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:
