Introduction + + The IANA registries for the type values and sub-type values of the + BGP Extended Communities attribute were reorganized by [RFC7153]. As + a result, IANA maintains a registry entitled "BGP Transitive Extended + Community Types", which includes a range of type values (0x80-0x8F) + reserved for Experimental Use [RFC8126]. Out of this experimental + range, types 0x80, 0x81, and 0x82 have been used in [RFC5575] and + [RFC7674] (both documents were rendered obsolete by [RFC8955]). The + primary use for those types and the sub-type registries is non- + experimental. + + Section 2 describes updates to the registry to reflect the actual use + of those code points by changing the registration procedure from + "Experimental Use" to "First Come First Served" [RFC8126] 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 has added RFC 9184 to the reference of this registry. + They have also updated the name of the type values according to + Table 1 and added RFC 9184 as a reference for the existing entries. + + +=======+==============================================+===========+ + | Type | Name | Reference | + | Value | | | + +=======+==============================================+===========+ + | 0x80 | Generic Transitive Extended Community (Sub- | RFC 9184 | + | | Types are defined in the "Generic Transitive | | + | | Extended Community Sub-Types" registry) | | + +-------+----------------------------------------------+-----------+ + | 0x81 | Generic Transitive Extended Community Part 2 | RFC 9184 | + | | (Sub-Types are defined in the "Generic | | + | | Transitive Extended Community Part 2 Sub- | | + | | Types" registry) | | + +-------+----------------------------------------------+-----------+ + | 0x82 | Generic Transitive Extended Community Part 3 | RFC 9184 | + | | (Sub-Types are defined in the "Generic | | + | | Transitive Extended Community Part 3 Sub- | | + | | Types" registry) | | + +-------+----------------------------------------------+-----------+ + + Table 1: Registry: BGP Transitive Extended Community Types + + Furthermore, IANA has changed the registration procedures of this + registry for type values 0x80 through 0x82 to First Come First Served + [RFC8126].
