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.
