Hi Jeff, and folks,
(cc-ing BESS and BESS chairs) Speaking as BESS chair, we think that there could be value to merge draft-ietf-bess-ebgp-dmz and draft-ietf-idr-link-bandwidth. draft-ietf-bess-ebgp-dmz is currently informational and covers two things: * Allowing non-transitive LBW to be sent over eBGP: I think the LBW IDR draft covers this in 3.1: "Note: Implementations MAY provide a configuration option to send non- transitive Link Bandwidth extended communities on external BGP sessions." * Allowing some maths on the LBW of contributing multipaths and advertising the computed value: the current IDR draft introduces this in 3.4. These maths are essentially a local behavior, we can give an example, but likely this doesn't require standardization. Based on that draft-ietf-bess-ebgp-dmz becomes more a use case draft rather than a draft which is specifying some new behavior and as BESS chairs, we want to avoid this. draft-ietf-bess-ebgp-dmz will require significant text rework if it needs to move forward as it makes some assumptions about IDR LBW draft which are not true anymore. We would like to hear opinions of both working group.

Please respond to the list whether you think the document is ready to be advanced for publication. -- Jeff (shepherding chair) On Jul 11, 2025, at 11:01 AM, Jeffrey Haas <[email protected] <mailto:[email protected]> > wrote: https://datatracker.ietf.org/doc/draft-ietf-idr-link-bandwidth/ This begins the working group last call for the link bandwidth extended community draft. Thanks to the authors for working their way through the substantive items that have been obstacles to interoperability over the years. This last call ends a week after IETF 123 to give the working group time to review and also take advantage of the focus time that IETF meeting weeks bring to our work. An item in particular we'd like to request particular attention to from the working group's review are the procedures covering default behaviors and interactions with deployments with mixed transitivities. The current draft text works to try to accommodate maximal backward compatibility with various deployment scenarios, but such text is tricky. For purposes of the shepherd's report and according to IETF BCP 78/79, the authors are requested to declare whether they are aware of any undisclosed IPR covering this draft. Members of the working group are similarly obligated to report any they are aware of as well. -- Jeff (for the IDR Chairs) _______________________________________________ Idr mailing list -- [email protected] <mailto:[email protected]> To unsubscribe send an email to [email protected] <mailto:[email protected]>
