Technical Summary
BGP communities (RFC 1997) are used by service providers for many
purposes, including tagging of customer, peer, and geographically
originated routes. Such tagging is typically used to control the
scope of redistribution of routes within a provider's network, and to
its peers and customers. With the advent of large scale BGP data
collection (and associated research), it has become clear that the
information carried in such communities is essential for a deeper
understanding of the global routing system. This document defines
standard (outbound) communities and their encodings for export to BGP
route collectors.
