We're not going to explode It'll be interesting to see if those NPE-G1s can handle all the DSL/cable multihomers and all the flapping. AO> the table to 2 million routes by this evening. It still takes its No, but if word got out that people could multihome effectively between cable and DSL, it'd happen pretty darn quickly. AO> time. You always had to upgrade to keep up with [speed, pps, routes, AO> features] and it's not going to change. Get over it. I'm not saying AO> only a Cisco CRS-1 or Juniper M640 can handle it. No, but people will resist something that their reasonably-new NPE-G1s and M40s can't handle. Get over it. AO> 1) How does this deal with local loop failures and other routing trouble? AO> Think very hard. You see? If you have followed the thread, you will note that this has been addressed. AO> Well, the policy and some aspects of the implementation have to change AO> anyway. AO> Why not do it in a way that at least scales before we hit the other AO> brickwall? I have proposed something that can be done _today_ with existing equipment (except for minor CPE changes). "Buy all new hardware each time someone wants or needs a feature" is not eaxactly scalable, either. Of course, what would I know? I've never been tasked with installing 2000 new line cards because someone failed to exploit a possibility for increased efficiency c/o simple policy decisions. You're simply shifting costs to hardware. If the bottom line is cheaper than providers cooperating, great. I'm not convinced that it is. Your kneejerk "buy more hardware" response is foolish and short-sighted: At the end of the day, _someone_ has to pay for everything. Why not seek the best cost/benefit? Prefix count is a concern. Let's say that IP space had been allocated in such a manner that each ASN has only one prefix. (This could have been achieved through better allocation practices. I digress.) That would be a global table roughly 10% what it is now. If you're going to cite Moore's law, keep this in mind: A factor of 10 is more than three Moore cycles, or roughly five years. That's not something just to blow off. You suggest exact-match lookup because it is efficient. I agree. I'm suggesting administrative policies that are efficient. The two are not mutually exclusive.
