BGP Extended Community Registries Update
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
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 Value | Name | Reference |
---|---|---|
0x80 | Generic Transitive Extended Community (Sub-Types are defined in the "Generic Transitive Extended Community Sub-Types" Registry) | [add this document] |
0x81 | Generic Transitive Extended Community Part 2 (Sub-Types are defined in the "Generic Transitive Extended Community Part 2 Sub-Types" Registry) | [add this document] |
0x82 | Generic Transitive Extended Community Part 3 (Sub-Types are defined in the "Generic Transitive Extended Community Part 3 Sub-Types" Registry) | [add this document] |
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 |
2.2. Registry: Generic Transitive Experimental Use Extended Community Sub-Types
IANA maintains a registry entitled "Generic Transitive Experimental Use Extended Community Sub-Types". IANA is requested update the registry title to:¶
- "Generic Transitive Extended Community Sub-Types"¶
2.3. Registry: Generic Transitive Experimental Use Extended Community Part 2 Sub-Types
IANA maintains a registry entitled "Generic Transitive Experimental Use Extended Community Part 2 Sub-Types". IANA is requested update the 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 update the registry title to:¶
- "Generic Transitive Extended Community Part 3 Sub-Types"¶
3. Security Considerations
There are no direct security considerations arising from this document.¶
