Abstract

Systems and methods at a reflector node include steps of receiving a request from an initiator node in the network, the request having been sent in a forward direction from the initiator node to the reflector node to discover a reverse path in a reverse direction from the reflector node to the initiator node, and transmitting a reply to the initiator node with one or more reverse Segment Routing (SR) policies that meet one or more path constraint parameters in the request. The reply can include associated Segment Identifiers (SIDs) for the one or more reverse SR policies. The steps can further include implementing one of Bidirectional Forwarding Detection (BFD) or a Multi-Protocol Label Switching (MPLS) Ping procedure with the initiator node, sent over one of the one or more reverse SR policies.
