Internet Neutral Exchange Association CLG LONAP Ltd This document describes a BGP Well-known Community called NO_EXPORT_VIA_RS. This community allows BGP route server clients to instruct an Internet Exchange BGP Route Server to tag prefixes destined for other route server clients with the NO_EXPORT Well-Known Community. This mechanism allows route server clients to transitively control distribution of their prefixes in other Autonomous Systems connected to the Internet Exchange Route Server.
