Configuring Route Pinning

By configuring the route pinning function, you can use the path that is originally selected, rather than another eligible path, to set up a CR-LSP.

Perform the following configurations on the ingress node of an MPLS TE tunnel.

If route pinning is enabled, the MPLS TE re-optimization cannot be used at the same time.

Run system-view
The system view is displayed.
Run interface tunnel interface-number
The tunnel interface view of the MPLS TE tunnel is displayed.
Run mpls te route-pinning
Route pinning is enabled.

By default, route pinning is disabled.
Run mpls te commit
The current tunnel configuration is committed.
