IGP Flexible Algorithm with Link Packet Loss

groupnone stateactive pages9 rev05 expires2026-09-03 canonicalhttps://datatracker.ietf.org/doc/draft-wang-lsr-flex-algo-link-loss/

This document proposes extensions to the IGP Flexible Algorithm. It introduces a mechanism to exclude links exceeding a specified packet loss rate threshold during path computation. The solution leverages existing link packet loss advertisement via IS-IS and OSPF, and defines new constraints for Flex-Algorithm path calculation.
