   This document describes the use of a well-known Border Gateway    Protocol (BGP) community for destination-based blackholing in IP    networks.  This well-known advisory transitive BGP community named    "BLACKHOLE" allows an origin Autonomous System (AS) to specify that a    neighboring network should discard any traffic destined towards the    tagged IP prefix.
