BGP Regisries by IDR and other BGP WGs
draft-hares-idr-bgp-registries-01.txt
Abstract
The BGP Registries at IANA were set up as one of the earliest IANA
registries. Over time, the registries have become denoted as
requiring "standards action", "early allocation", "FCFS (first-come,
first served)", "vendor specific", and "IETF review". This draft
proposes that certain BGP registries that are labelled "standards
action", "early allocation", or "IETF Review" add to these
registration actions a "Expert Review. It also proposes that the
chairs of BGP Protocol related WG groups be part of the review team.
The intent is that these chairs will be responsible for bringing
questionable allocations to their workings attention.
The BGP relate working groups are currently the IDR, BESS, SIDROPS,
and GROW, but other working groups like SPRING might be added.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at http://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months

1. Introduction
During 2016, several BGP attributes were squatted upon causing
operational problems during the early deployment of large communities
[RFC8092]. Due these problems, [RFC8093] deprecated the use of 6
attribute numbers.
To avoid this problem in the future, it is helpful to increase pace
of the early-allocations process and to coordinate the review of key
BGP registries. This document proposes to augment existing
registration processes for BGP registries with Expert review.
This draft proposes that certain BGP registries that are labelled
"standards action", "early allocation", or "IETF Review" add to these
registration actions a "Expert Review. It also recommends that the
chairs of BGP Protocol related WG groups be part of the review team.
2. BGP Registries to Change Registration Process on
This document proposes the that IETF BGP registries in Table 1 below
require their current registration policy plus Expert Review. It
recommends that the chairs of the BGP related working groups (e.g.
IDR, Bess, SIDROPS, GROW) be a part of this review team. The IESG
can define which working groups are BGP working groups, but it is
important to get the chairs of the Working Groups that originate or
maintain the drafts in Table 1 as part of the review team.

If no BGP WG groups remain, the IESG may select designated experts to
fulfill this role.

The registries in Table 2 have Expert Review. This document requests
that IANA increase their designated expert pool by adding to the pool
the chairs in BGP related Working Groups (E.g. IDR, BESS, SIDROPS,
GROW).
