Subject: [Idr] WG adoption for draft-kumari-deprecate-as-set-confed-set - 8/16 to 8/30/2019
Resent-From: <keyur@arrcus.com>;

Greetings:

This begins a 2 week WG adoption call for draft-kumari-deprecate-as-set-confed-set
from 8/16 to 8/30/2019.

This draft seeks to remove AS_SET and AS_CONFED_SET from RFC4271.
Draft is at:
https://tools.ietf.org/html/draft-kumari-deprecate-as-set-confed-set-14


To quote the draft:


   “BCP 172<https://tools.ietf.org/html/bcp172> [RFC6472<https://tools.ietf.org/html/rfc6472>;] makes a recommendation for not using AS_SET and

   AS_CONFED_SET in Border Gateway Protocol (BGP).  This document

   advances the recommendation to a standards requirement in BGP”
        [aka RFC4271].



   “From analysis of past Internet routing data, it is apparent that

   aggregation that involves AS_SETs is very seldom used in practice on

   the public Internet [Analysis<https://tools.ietf.org/html/draft-kumari-deprecate-as-set-confed-set-14#ref-Analysis>;] and when it is used, it is often used

   incorrectly -- reserved AS numbers ([RFC1930<https://tools.ietf.org/html/rfc1930>;]) and/or only a single

   AS in the AS_SET are by far the most common cases.”





In your comments on adoption, consider:



1)  Should the IDR WG remove AS_SET and AS_CONFED_SET from BGP?

#Keyur: Yes.



2)  Is this document a reasonable document to document that removal?

#Keyur: Yes.



3)  Are there technical flaws in the arguments for removal?

4)  Are there issues with the text?

#Keyur: No.



Regards,

Keyur



Cheerily, Susan Hares
