IGP Flexible Algorithm
RFC 9350

Received changes through RFC Editor sync (created alias RFC 9350, changed abstract to 'IGP protocols historically compute the best paths over the network based on the IGP metric assigned to the links.  Many network deployments use RSVP-TE or Segment Routing - Traffic Engineering (SR-TE) to steer traffic over a path that is computed using different metrics or constraints than the shortest IGP path.  This document specifies a solution that allows IGPs themselves to compute constraint-based paths over the network.  This document also specifies a way of using Segment Routing (SR) Prefix-SIDs and SRv6 locators to steer packets along the constraint-based paths.', changed pages to 42, changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2023-02-22, changed IESG state to RFC Published)
