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 is thus
misleading.
This document updates RFC7153 RFCs 7153 and RFC8955. 8955.

1. Introduction
[RFC7153] reorganizes the
The IANA registries for the type values and sub-type values of the
BGP Extended Communities attribute. attribute were reorganized by [RFC7153]. As
a
result the result, IANA maintained maintains a registry entitled "BGP Transitive Extended
Community Types" Types", which includes a range of Type Values type values (0x80-0x8F)
reserved for Experimental Use. Use [RFC8126]. Out of this experimental range the
range, types 0x80, 0x81, and 0x82 have been used in [RFC5575] and
[RFC7674] (both documents were rendered Obsolete obsolete by [RFC8955]). The
primary use for those types and the sub-type registries is non non-
experimental.
Section 2 of this document requests describes updates to the registry cleanup to reflect the actual use
of those code-points (removing "Experimental Use" from
the sub-type registry names) and changes code points by changing the registration procedure
of the types 0x80, 0x81, 0x82 from
"Experimental Use" to use the First "First Come First Served
policy Served" [RFC8126] and thus updates for the
types 0x80-0x82 (and removing "Experimental Use" from the sub-type
registry names), thereby updating [RFC7153] and [RFC8955].
2. IANA Considerations
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] has added RFC 9184 to the Reference reference of this registry, update registry.
They have also updated the Name name of the Type Values type values according to
Table 1 and append added RFC 9184 as a reference to [this document] to for the existing
references. entries.
+=======+==============================================+===========+
| Type | Name | Reference |
| Value | | |
+=======+==============================================+===========+
| 0x80 | Generic Transitive Extended Community (Sub- | [add this RFC 9184 |
| | Types are defined in the "Generic Transitive | document] |
| | Extended Community Sub-Types" registry) | |
+-------+----------------------------------------------+-----------+
| 0x81 | Generic Transitive Extended Community Part 2 | [add this RFC 9184 |

Table 1: Registry: BGP Transitive Extended Community Types
Furthermore
Furthermore, IANA is requested to change has changed the registration procedures of this
registry of Type Values for type values 0x80 thru through 0x82 to First Come First Served
[RFC8126]. The resulting Registration Procedures registration procedures should read as in
Table 2.
+===========+===============================================+

+-----------+-----------------------------------------------+
| 0x80-0x82 | First Come First Served (see [this document]) RFC 9184) |
+-----------+-----------------------------------------------+
| 0x83-0x8f | Reserved for Experimental Use (see [RFC3692]) |
