From: "Milo S. Medin" (NASA ARC NSI Office) <medin@nsipo.nasa.gov> Subject: Re: 20402 routing entries We use the same techniques we are doing today. If we reduce specific advertisements from 500 to 2, instead of 500 to 1, we still win. Milo, In the worst case it stays at 500 to 500.. you're forcing people to renumber to deal with one transit network's AUP. If I was responsible for the Latvian national backbone, and I demanded that you gave up CIDR benefits or force your customers to renumber, wouldn't you be a bit irked? Enforcing the AUP -must- be the sole responsibility of the network that has the AUP constraints. That's the way everyone else has been doing things. We got away with the NSF AUP because we still had a strong concept of a core. Heck, how many of us still (until recently) called the NSFnet the "backbone"? I know I did. There is no "core" anymore, NSF, ES, and NSI are transit clouds in a tangled web. If someone needs to play policy games, they, and their customers, should be the ones forced to pay for it. Paul
