How many backbone NSP's would use a bgp aggreation tool that was setup similar to the route-views.oregon-ix.net or route-server.cerf.net that you would be able to do queries on to say "what might I not be aggregating correctly?" I'm working on such a tool that would be able to speak eBGP to a router (multihop or otherwise) and give this information. I've noticed a few providers that have /16's that announce each specific /24 or almost each one also, this would also make it possible to generate lists of folks that clog the routing table. I've sent e-mail to some of these folks today... Please direct responses directly to me if you're interested, or if you have something useful on this topic for *everyone* on nanog, include them also. - Jared -- ----------------- jared@puck.nether.net - Nether Network ------------------ CICNet/IAGNet/QUALnet/NetherNet - finger jared@puck.nether.net for pgp key
