Maintaining the current best practices with communities, ISPs and enterprises that are assigned a 4-octet AS number may want the BGP UPDATE messages they receive from their customers or peers to include a 4-octet AS specific BGP extended community. This document defines a new sub-type within the four-octet AS specific extended community to facilitate this practice.
