A Segment Routing (SR) Policy Candidate Path can contain multiple Segment Lists, allowing for load-balancing and protection across diverse paths. However, current PCEP extensions for SR Policy only allow signaling of a single Segment List per Candidate Path. This document defines PCEP extensions to encode multiple Segment Lists within an SR Policy Candidate Path, enabling multipath capabilities such as weighted or equal-cost load-balancing across Segment Lists. The extensions are designed to be generic and reusable for future path types beyond SR Policy, and are applicable to both stateless and stateful PCEP.
