IDR Working Group C. Loibl Internet-Draft next layer Telekom GmbH Updates: 7153 (if approved) 13 October 2021 Intended status: Standards Track Expires: 16 April 2022 BGP Extended Community Registries Update draft-ietf-idr-bgp-ext-com-registry-03 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.

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]. 2. IANA Considerations Loibl Expires 16 April 2022 [Page 2] Internet-Draft BGP Ext. Com. Registries Update October 2021 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 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 | +-----------+-----------------------------------------------+ Table 2: Registration Procedures: BGP Transitive Extended Community Types Loibl Expires 16 April 2022 [Page 3] Internet-Draft BGP Ext. Com. Registries Update October 2021 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. 5. References 5.1.
