Configuring route pinning

When route pinning is enabled, MPLS TE tunnel reoptimization is not available.

Perform this task on the ingress node of an MPLS TE tunnel.

mpls te route-pinning

By default, route pinning is

Configuring tunnel reoptimization

Tunnel reoptimization allows you to manually or dynamically trigger the ingress node to recalculate a

path. If the ingress node recalculates a better path, it creates a new CRLSP, switches the traffic from the

old CRLSP to the new CRLSP, and then deletes the old CRLSP.

Perform this task on the ingress node of an MPLS TE tunnel.
