1. A method comprising:
receiving, at a terminating node of a multi-protocol label switched (MPLS) network, an MPLS request message to validate connectivity in a network path of an MPLS network, wherein:
the MPLS request message includes a request for the terminating node to send a response message that identifies the terminating node to an initiating node;
the network path includes an intermediate node that sends traffic in a data plane of the network path to terminate on the terminating node or a second terminating node; and
the intermediate node is configured to route traffic having a particular label to the terminating node or the second terminating node;
generating the response message based at least in part on the request;
populating the response message with identification data that includes a unique identifier of the terminating node; and
sending the response message via the network path to the initiating node.
