There is some work going on in IETF (itrace) to trace these attacks back even w/ spoofed ips, etc.. There are currently no "poison" bgp updates you can send upstream to get them to blackhole the traffic. - Jared On Thu, May 31, 2001 at 05:59:18PM -0400, Andrew Dorsett wrote:
Hey, this is a technical question for all of the Network Engineers/Architects on the list. Has a method been found to stop an incoming attack? Granted you can filter the packets to null on the router, but that doesn't stop them from coming across the wire and into the router. Has a way been devised to stop them from coming into the router; via something like a BGP update to null the packets or what? I'm concerned about a flood that is so massive coming from the core and flooding a small T1 or less.
