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.

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 https://datatracker.ietf.org/drafts/current/.

Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."

This Internet-Draft will expire on 3 August 2021.

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.

Table 1: Registry: BGP Transitive Extended Community Types
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.

Table 2: Registration Procedures: BGP Transitive Extended Community Types
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.

4. Acknowledgements

The author wants to thank Alvaro Retana, who pointed out, that the IANA registry contains misleading entries in this context.
