Randy Bush is rumoured to have written: * the problem is that routers will not run acls of the size needed to filter * large peers were they to register. so why should i whine at them to * register. whine at who? the large peers? they should register so that when one notices something odd, one can query to see what it _should_ be. they should register, and maintain their registrations, so that in an ideal world, their announcements would match what they have registered, and be nicely aggreagted, too! i emphatically DO NOT think that large providers should filter other peers. i think the large providers should filter their own announcements, by carefully verifying what a downstream wishes to announce before accepting it, filtering the customer announcements, and aggregating their announcements to peers. i think its silly to try and regulate the world from ones own corner. regulate your corner, and encourage others to do the same. i don't care if said encouragement is by tacit agreememnt, or bound up in legealese in peering agreements. * there used to be a provider which configured their routers to statically * route based on the registry. that provider is gone. a lot of things are gone. but then, was it really their routing policies that killed them, in the end? _k
