The IESG has received a request from the Open Shortest Path First IGP WG (ospf) to consider the following document: - 'OSPF Extensions for Segment Routing' <draft-ietf-ospf-segment-routing-extensions-19.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-10-13. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Segment Routing (SR) allows a flexible definition of end-to-end paths within IGP topologies by encoding paths as sequences of topological sub-paths, called "segments". These segments are advertised by the link-state routing protocols (IS-IS and OSPF). This draft describes the OSPF extensions required for Segment Routing.
