How irresponsible can you get? Advertising bogus routes, not taking any action about it when notified, obviously not having even the most minimal filters in place to prevent such things. Doesn't give me much confidence in the stability of their network or in their protections against accidental (either clueless or oops) or deliberate bogosity. Obviously, this particular instance is of little real consequence and is trivial for clueful providers to filter, but it is symptomatic of a system that may well have bigger holes large enough to drive the Titanic through as it sinks. It would be interesting to do a survey to see just how many backbone providers you can convince to advertise a really dumb route, a route for a block you don't own and is obviously in use elsewhere, etc. If this is what we see from a major backbone, what should we expect from Joe's ISP and Steak House in Mudfest Wyoming? It seems that no progress has been made, in North America as a whole, since previous incidents. Not only is it an exact reverse of one of their blocks, but it is (logically) routed there. If you trace from a silly network that doesn't filter the announcement: 6 sl-bb11-sea-2-1.sprintlink.net (144.232.6.21) 3.612 ms 3.437 ms 3.921 ms 7 sl-bb2-sea-8-0-0.sprintlink.net (144.232.6.30) 4.067 ms 4.427 ms 4.642 ms 8 sl-bb5-chi-5-0-0.sprintlink.net (144.228.10.62) 43.526 ms 43.728 ms 43.595 ms 9 sl-bb11-chi-0-2.sprintlink.net (144.232.0.173) 43.276 ms 42.518 ms 43.166 ms 10 sl-bb4-chi-4-0-0.sprintlink.net (144.232.0.166) 43.811 ms 43.082 ms 44.367 ms 11 144.228.252.11 (144.228.252.11) 67.481 ms 67.477 ms 69.302 ms 12 sl-paterno-2-0-128k.sprintlink.net (144.228.52.2) 76.157 ms 76.420 ms 74.786 ms On Thu, 17 Sep 1998 steve@altrina.exodus.net wrote:
