Configuring Crlsp Backup - HP HPE FlexNetwork MSR Router Series Configuration Manual

•
To set up a bidirectional MPLS TE tunnel in co-routed mode, you must specify the signaling
protocol as RSVP-TE.
To create a bidirectional MPLS TE tunnel, create an MPLS TE tunnel interface on both ends of the
tunnel and enable the bidirectional tunnel function on the tunnel interfaces:
•
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 CRLSP at the passive end.
•
For an associated bidirectional tunnel, specify a reverse CRLSP at both ends of the tunnel.
To configure the active end of a co-routed bidirectional MPLS TE tunnel:
Step
1. Enter system view.
2. Enter MPLS TE tunnel
interface view.
3. Configure a co-routed
bidirectional MPLS TE tunnel
and specify the local end as
the active end of the tunnel.
To configure the passive end of a co-routed bidirectional MPLS TE tunnel:
Step
1. Enter system view.
2. Enter MPLS TE tunnel
interface view.
3. Configure a co-routed
bidirectional MPLS TE tunnel
and specify the local end as
the passive end of the tunnel.
To configure an associated bidirectional MPLS TE tunnel:
Step
1. Enter system view.
2. Enter MPLS TE tunnel
interface view.
3. 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:
Command
system-view
interface tunnel tunnel-number
[ mode mpls-te ]
mpls te bidirectional co-routed

Command
system-view
