IDR, BESS, During the work driven by draft-ietf-idr-link-bandwidth, the issue of originating non-transitive was brought up and partially discussed in the use case work for draft-ietf-bess-ebgp-dmz. As discussed during IDR sessions at IETFs 122 and 123, the preferred solution for addressing the ambiguities in non-transitivity was to do a small -bis for RFC 4360. Nat Kao has kindly agreed to be our editor to move this process along. This document, and issues vs. it, will be managed in the IDR github.[1]
Since this is IDR chair commissioned work to address this gap, it's our intention to adopt this work. However, the chairs would like to provide a review period to OBJECT to adoption. That said, if you'd like to offer support for the work, or other technical comments, please do so in this thread! This adoption check ends on 5 September. Please note this overlaps the US Labor Day holiday and consider that in the timing of your request, in case that's relevant. The scope of the commissioned work is: - Address open errata vs. RFC 4360 - Address the origination and reception of non-transitive routes across eBGP boundaries. The current text of the draft currently addresses these items. As part of reviewing this problem, the IETF archives show that there was prior work covering this issue in draft-decraene-idr-rfc4360-clarification-00 [2]. We've made sure to acknowledge those prior efforts in the -bis and would request review from those authors on this -bis. -- Jeff (for the IDR Chairs) [1] https://github.com/ietf-wg-idr/draft-ietf-idr-rfc4360-bis <https://github.com/ietf-wg-idr/draft-ietf-idr-rfc4360-bis> [2] Bruno and company are to be commended for pressing this issue for several years. While prior IDR mail threads seem to suggest "this works fine was the answer", the fact that we had non-transitive behaviors as a point of contention in the BESS LBW work means it's past time to enshrine fixing the original criticisms in an RFC update. > Begin forwarded message: > > From: [email protected] > Subject: I-D Action: draft-chairs-idr-rfc4360-bis-00.txt > Date: August 22, 2025 at 2:46:40 PM EDT > To: <[email protected]> > Reply-To: [email protected] > > Internet-Draft draft-chairs-idr-rfc4360-bis-00.txt is now available. > > Title: BGP Extended Communities Attribute > Author: Nat Kao > Name: draft-chairs-idr-rfc4360-bis-00.txt > Pages: 13 > Dates: 2025-08-22 > > Abstract: > > This document describes the "extended community" BGP-4 attribute. > This attribute provides a mechanism for labeling information carried > in BGP-4.
