The IESG has approved the following document: - 'OSPF Extensions for Segment Routing' (draft-ietf-ospf-segment-routing-extensions-24.txt) as Proposed Standard This document is the product of the Open Shortest Path First IGP Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-ospf-segment-routing-extensions/ Technical Summary This document describes the OSPFv2 extensions for segment routing including Prefix-SID, Adjacency-SID, and Binding-SID. The extensions are based on RFC 7770. Working Group Summary The Working Group discussion has been dominated by the initial vendors that implemented the specification (Juniper, Cisco, and Nokia). We've gone through several iterations over the last two and half years. The document has completed two separate IPR polls. It is in its second Working Group last call due to some additional protocol encodings and clarifications on the handling of error situations. The second Working Group last call is preceding without questions or significant comments. The ERO and binding-SID extensions were removed due to AD comments and these changes were Working Group last called. Document Quality The document has been implemented by a number of vendors (refer to the implementation status section) and has been stable now for a few months. In fact, the only changes have been edits and clarifications based on WG last-call and chair review. Personnel Acee Lindem is the Document Shepherd. Alia Atlas is the Responsible Area Director.
