BGP Extended Community Registries Update
draft-ietf-idr-bgp-ext-com-registry-05
Abstract
This document updates several BGP Extended Community registries in
order to replace the "Experimental Use" registration procedure in
some entries, since their use is clearly not experimental and thus
misleading.
This document updates RFC7153 and RFC8955.

1. Introduction
[RFC7153] reorganizes the IANA registries for the type values and
sub-type values of the BGP Extended Communities attribute. As a
result the IANA maintained registry entitled "BGP Transitive Extended
Community Types" includes a range of Type Values (0x80-0x8F) reserved
for Experimental Use. Out of this experimental range the types 0x80,
0x81, 0x82 have been used in [RFC5575] and [RFC7674] (both documents
rendered Obsolete by [RFC8955]). The primary use for those types and
sub-type registries is non experimental.
Section 2 of this document requests the registry cleanup to reflect
the actual use of those code-points (removing "Experimental Use" from
the sub-type registry names) and changes the registration procedure
of the types 0x80, 0x81, 0x82 to use the First Come First Served
policy [RFC8126] and thus updates [RFC7153] and [RFC8955].

Internet-Draft BGP Ext. Com. Registries Update December 2021
2.1. Registry: BGP Transitive Extended Community Types
IANA maintains a registry entitled "BGP Transitive Extended Community
Types". IANA is requested to add [this document] to the Reference of
this registry, update the Name of the Type Values according to
Table 1 and append a reference to [this document] to the existing
references.
+=======+==============================================+===========+
| Type | Name | Reference |
| Value | | |
+=======+==============================================+===========+
| 0x80 | Generic Transitive Extended Community (Sub- | [add this |
| | Types are defined in the "Generic Transitive | document] |
| | Extended Community Sub-Types" registry) | |
+-------+----------------------------------------------+-----------+
| 0x81 | Generic Transitive Extended Community Part 2 | [add this |
| | (Sub-Types are defined in the "Generic | document] |
| | Transitive Extended Community Part 2 Sub- | |
| | Types" registry) | |
+-------+----------------------------------------------+-----------+
| 0x82 | Generic Transitive Extended Community Part 3 | [add this |
| | (Sub-Types are defined in the "Generic | document] |
| | Transitive Extended Community Part 3 Sub- | |
| | Types" registry) | |
+-------+----------------------------------------------+-----------+
Table 1: Registry: BGP Transitive Extended Community Types
Furthermore IANA is requested to change the registration procedures
of this registry of Type Values 0x80 thru 0x82 to First Come First
Served [RFC8126]. The resulting Registration Procedures should read
as in Table 2.
+===========+===============================================+
| Range | Registration Procedures |
+===========+===============================================+
| 0x00-0x3f | First Come First Served |
+-----------+-----------------------------------------------+
| 0x80-0x82 | First Come First Served (see [this document]) |
+-----------+-----------------------------------------------+
| 0x83-0x8f | Reserved for Experimental Use (see [RFC3692]) |
+-----------+-----------------------------------------------+
| 0x90-0xbf | Standards Action |
+-----------+-----------------------------------------------+

Use Extended Community Sub-Types". IANA is requested to add [this

title to:
"Generic Transitive Extended Community Sub-Types"
2.3. Registry: Generic Transitive Experimental Use Extended Community
Part 2 Sub-Types

registry title to:
"Generic Transitive Extended Community Part 2 Sub-Types"
2.4. Registry: Generic Transitive Experimental Use Extended Community
Part 3 Sub-Types
IANA maintains a registry entitled "Generic Transitive Experimental
Use Extended Community Part 3 Sub-Types". IANA is requested to add
[this document] to the Reference of this registry and update the
