Abstract

Segment Routing (SR) allows a node to steer a packet flow along anypath. Intermediate per-path states are eliminated thanks to sourcerouting. SR Policy is an ordered list of segments (i.e.,instructions) that represent a source-routed policy. Packet flows aresteered into an SR Policy on a node where it is instantiated called aheadend node. The packets steered into an SR Policy carry an orderedlist of segments associated with that SR Policy.

This document updates RFC 8402 as it details the concepts of SRPolicy and steering into an SR Policy.
