This document describes the use of a well-known Border Gateway Protocol (BGP) community for blackholing at IP networks and Internet Exchange Points (IXP). This well-known advisory transitive BGP community, namely BLACKHOLE, allows an origin AS to specify that a neighboring IP network or IXP should blackhole a specific IP prefix.
