• 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:
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:
