The IESG has approved the following document: - 'IPv6 Segment Routing Header (SRH)' (draft-ietf-6man-segment-routing-header-26.txt) as Proposed Standard
This document is the product of the IPv6 Maintenance Working Group. The IESG contact persons are Éric Vyncke and Suresh Krishnan. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-6man-segment-routing-header/ Technical Summary Segment Routing is designed to be applied to the IPv6 data plane using a new type of Routing Extension Header (SRH) in this document. This document describes the Segment Routing Extension Header and how it is used by Segment Routing capable nodes. The Segment Routing Architecture [RFC8402] describes Segment Routing and its instantiation in two data planes MPLS and IPv6. The encoding of IPv6 segments in the Segment Routing Extension Header is defined in this document. Working Group Summary The work on SRH has been underway for a long time. The first working group version of the draft was published in December 2015, the first working group call started on March 2018. Given the number of issues that were raised the chairs started an issue tracker. Fifty issues were tracked. After further discussion, many new drafts, and confirmation at IETF 104, the chairs started a second working group last call in May 2019. After further discussion two new drafts were published and the chairs concluded the last call and declared that there is consensus to advance this document on 14 June 2019. See: https://mailarchive.ietf.org/arch/msg/ipv6/_9OrqvZYpDB0lJEE8jxB0a0N44M The chairs believe there is a strong consensus to advance this document, but it was not unanimous. There remains a desire by a few people to add more clarity on mutability of segment lists and other fields. The chairs conclusion is that the text added since the last call closes this topic, but a few would like to see more. Document Quality Section 9 lists current implementations, these include: Linux Kernel v4.14 Cisco Systems IOS XR and IOS XE FD.io VPP/Segment Routing for IPv6 Barefoot Networks Tofino NPU Detailed reviews were done in the course of review this document in the 6man working group. Several people did extensive reviews, they include Joel Halpern, Ron Bonica, Mark Smith, and Tom Herbert. The 6man chairs have also reviewed this document. These reviews resulted in many improvements to the document. No MIBs or other media types to be reviewed. Personnel Bob Hinden is the Document Shepherd. Suresh Krishnan is the Responsible AD. _______________________________________________ IETF-Announce mailing list [email protected] https://www.ietf.org/mailman/listinfo/ietf-announce
