BGP Extended Community Registries Update
draft-cl-idr-bgp-ext-com-registry-update-01
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.

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) with
Experimental Use registration procedure. Out of this experimental
range the types 0x80, 0x81, 0x82 have been assigned via [RFC5575] and
[RFC7674]. 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 first come first serve.
2. IANA Considerations

Internet-Draft BGP Ext. Com. Registries Update April 2020
2.1. Registry: BGP Transitive Extended Community Types
IANA maintains a registry entitled "BGP Transitive Extended Community
Types". IANA is requested to 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
Serve. 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 |
+-----------+-----------------------------------------------+
