Systems and methods, associated with a Segment Routing network including a plurality of nodes in a ring, include defining a first Flexible Algorithm having one or more first constraints for links in the ring to force traffic to flow in a first direction around the ring; and defining a second Flexible Algorithm having one or more second constraints for of the links in the ring to force traffic to flow in a second direction around the ring. A Path Computation Engine (PCE) is configured to group links on the computed path to the one or more rings, for each ring, determine a direction on an associated ring and assign the grouped links on the associated ring with a Flex-Algo SID for a final node in the determined direction, and provide a SID list that includes the Flex-Algo SIDs for the one or more rings, to a source node in a Segment Routing network.
