BGP Flow-Spec Redirect to SR Segment List Action

BGP Flow Specification (Flow-spec) provides a mechanism for distributing traffic filtering and policy-based forwarding rules. Existing works enables traffic steering into an SR Policy. However, in Artificial Intelligence (AI) network scenarios, "elephant flows" may require deterministic forwarding over specific segment lists within an SR Policy candidate path. This document specifies a new BGP Flow-spec Redirect action that identifies a specific segment list within an SR Policy.
