Usage guidelines
Route recording records the nodes that an MPLS TE tunnel traverses. Label recording records the label assigned by each node. The recorded information helps you know about the path used by the MPLS TE tunnel and the label distribution information. When the tunnel fails, the recorded information helps you locate the fault.
