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.

[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.
