No. You cannot influence the inbound traffic apart from not advertising some of your prefixes to some of your neighbors or giving them hints with BGP communities or AS-path prepending. Whatever you do with BGP on your routers

actually need is remote-triggered black hole. Search the Nanog archives for RTBH, you'll find a number of links in a message from Frank Bulk sent a few
days ago.


Or, you can prepend your advertisement with the troublesome ASN.

Works for one or two troublesome ASNs as a quick hack at 3am - don't do it unless you understand why it works and why you shouldn't do it.
