Systems and methods for enhancing Segment Routing (SR) protocols are provided for enabling the stitching of a remote SR policy to a local SR policy. A method can include obtaining a Segment Routing (SR) policy for routing a packet along a path in a downstream domain, the SR policy including at least a destination field and a color field, the destination field defining an end-point of the path in the downstream domain, the end-point representing a destination node or service instance, the color field defining the path in the downstream domain, and storing the SR policy in the database.

Systems and methods for inducing a recovery of a service along a shorter path are provided. In one embodiment, a system having a processing device and a memory device is disclosed. The memory device is configured to store software logic including instruction that, when executed, enable the processing device to determine there is a defect in a primary Segment Routing (SR) to a main destination. The instructions further enable the processing device to identify an available path to an alternative destination that is shorter than a backup SR path to the main destination. Also, a main service associated with the main destination is switched over to an alternative service associated with the alternative destination based on the determining and the identifying.
