RFC 3882
Title: Configuring BGP to Block Denial-of-Service Attacks Author(s): D. Turk Status: Informational Date: September 2004 Mailbox: doughan.turk@bell.ca Pages: 8 Characters: 19637 Updates/Obsoletes/SeeAlso: None

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
This tunneling is 'centertrack' which is patented... Also, tunneling is a dangerous prospect when you get very large amounts of attack traffic.
