Given recent discussions on blackholing traffic, this may
be of interest.

This document describes an operational technique that uses BGP
communities to remotely trigger black-holing of a particular
destination network to block denial-of-service attacks.  Black-holing
can be applied on a selection of routers rather than all BGP-speaking
routers in the network.  The document also describes a sinkhole tunnel
technique using BGP communities and tunnels to pull traffic into a
sinkhole router for analysis.
