              IANA Registries for BGP Extended Communities

Abstract

   This document reorganizes the IANA registries for the type values and
   sub-type values of the BGP Extended Communities attribute and the BGP
   IPv6-Address-Specific Extended Communities attribute.  This is done
   in order to remove interdependencies among the registries, thus
   making it easier for IANA to determine which codepoints are available
   for assignment in which registries.  This document also clarifies the
   information that must be provided to IANA when requesting an
   allocation from one or more of these registries.  These changes are
   compatible with the existing allocations and thus do not affect
   protocol implementations.  The changes will, however, impact the
   "IANA Considerations" sections of future protocol specifications.
   This document updates RFC 4360 and RFC 5701.
