I would go at first by advertising your prefixes as a /24 as well, just randomly checked 2 different locations and the as-path to 11325 is shorter than to 33611 This seems to be the case for customers of Tiscali and L3, so this will probably get most of your traffic back to you... Regards, Ido --

If you both announce a /24, the BGP route selection process should begin to return some of the traffic to these prefixes back to your AS. Also, if you begin to advertise your prefixes as /24s and as a result, they try to advertise /25s, I would venture a guess that their /25s would get blocked enti

You can break your blocks into /24's or smaller and readvertise them to your upstreams. You can also modify local preference using community tags with most upstreams. If you have tier 1 peerings you may be able to get them to filter the bad routes if you can prove they were assigned to you by ARI

Many/most transit providers filter prefixes longer than /24, so the effectiveness may be minimal. At the very least I'd advertise /24s yourself because if the forger is geographically further away, some local sites may still work. Better than nothing. On Tue, Jan 31, 2012 at 11:19 AM, Grant Ri
