Routing Area IDR Working Group IANA 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 is thus misleading. This document updates RFCs 7153 and 8955.

Introduction The IANA registries for the type values and sub-type values of the BGP Extended Communities attribute were reorganized by . 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 . Out of this experimental range, types 0x80, 0x81, and 0x82 have been used in and (both documents were rendered obsolete by ). The primary use for those types and the sub-type registries is non-experimental. 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" for the types 0x80-0x82 (and removing "Experimental Use" from the sub-type registry names), thereby updating and .

IANA Considerations

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 and added RFC 9184 as a reference for the existing entries. 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)	RFC 9184
0x81	Generic Transitive Extended Community Part 2 (Sub-Types are defined in the "Generic Transitive Extended Community Part 2 Sub-Types" registry)	RFC 9184
0x82	Generic Transitive Extended Community Part 3 (Sub-Types are defined in the "Generic Transitive Extended Community Part 3 Sub-Types" registry)	RFC 9184

Furthermore, IANA has changed the registration procedures of this registry for type values 0x80 through 0x82 to First Come First Served . The resulting registration procedures should read as in . Registration Procedures: BGP Transitive Extended Community Types

Range	Registration Procedures
0x00-0x3f	First Come First Served
0x80-0x82	First Come First Served (see RFC 9184)
0x83-0x8f	Reserved for Experimental Use (see )
0x90-0xbf	Standards Action
