Claim 9:
10. A non-transitory computer-readable medium configured to store computer logic having instructions for performing a continuity test between a source node and a destination node, wherein, when executed, the instructions are configured to cause one or more processing devices to:
enter a first list of one or more Segment Identifiers (SIDs) into a Bidirectional Forwarding Detection (BFD) request packet, the first list of one or more SIDs defining a Segment-Routing Traffic-Engineering (SR-TE) forward path from the source node to the destination node,
enter a second list of one or more SIDs into the BFD request packet, the second list of one or more SIDs defining an SR-TE reverse path from the destination node to the source node, where involvement of a BFD reflector of the destination node is eliminated, and
enter a revised-BFD request into the BFD request packet, the revised-BFD request having a Your Discriminator field set to a discriminator value associated with the source node.
