So what? The newer 7200s have got NPE-G1's or soon NPE-G2's in them. Comes with 1G RAM default. It's not that your 7 year old NPE-150 can still participate in todays DFZ, is it? We're not going to explode the table to 2 million routes by this evening. It still takes its time. You always had to upgrade to keep up with [speed, pps, routes, features] and it's not going to change. Get over it. I'm not saying only a Cisco CRS-1 or Juniper M640 can handle it.

1) How does this deal with local loop failures and other routing trouble? Think very hard. You see? 2) You are missing the renumbering issue. Multihomed customer doesn't want renumber when he changes any of the ISPs in the mix. That's why everyone wants PI space.

Well, the policy and some aspects of the implementation have to change anyway. Why not do it in a way that at least scales before we hit the other brickwall? -- Andre
