Summary:Systems and methods provide congruent bidirectional Segment Routing (SR) tunnels, namely congruent and fate-shared traffic forwarding for bidirectional SR tunnels. A bidirectional SR tunnel, as described herein, includes two unidirectional SR tunnels where the forward and reverse traffic directions follow the same path through the network when forwarded based on prefix and adjacency Segment Identifiers (SIDs). The term "congruent" is used herein to refer to the fact that the two unidirectional SR tunnels, i.e., the forward and reverse traffic directions, follow the same path through the network but in opposite directions. The guarantee of congruency is based on modification of the Segment Identifier (SID) configuration at the source nodes of each tunnel. Accordingly, the present disclosure maintains compatibility with existing Segment Routing configurations with the modifications solely at the source nodes.
