So in IPv4 the magic is of sufficiently quality. route-views is run by competent people, and the networks who feed routing tables to it are usually run by competent people. filtering this kind of trash is probably a normal part of operations for this class of networks. i don't think you can use route-views as a poster child for filtering having been gotten right. -- Paul Vixie
