Abstract
Systems and methods for domain Border Router (BR) resiliency with segment compaction in Segment Routing include obtaining a compressed segment list for a calculated path in a Segment Routing network, wherein the Segment Routing network includes a plurality of domains with the calculated path being through at least two domains, wherein the compressed segment list includes a plurality of Segment Identifiers (SID) each SID identifying a segment, and wherein, when expanded, the compressed segment list matches the calculated path; analyzing the compressed segment list for any domain border routers between two domains of the at least two domains to determine associated anycast SID for the any domain border routers; and utilizing the associated anycast SID in the compressed SID list for resiliency between the two domains.
