Usage guidelines
When loop detection is enabled on the ingress node of an MPLS TE tunnel, the route recording feature is automatically enabled for the tunnel, regardless of whether the mpls te record-route command is configured. When establishing the MPLS TE tunnel, each node of the tunnel detects whether a loop has occurred according to the recorded route information.
Examples
