I would hope we all realise that CIDR is a sticking plaster and not the ultimate solution to the possible problems in the future ? I am certainly of that mind, and I think that "the CIDR working group" and all of us out here should not become the "Cisco workaround comittee". I don't understand why some folks continue to believe that CIDR is a band-aid or a "Cisco workaround" or some other such rot. That is an utter falacy. CIDR is the exponential growth in resource requirements workaround comittee. It doesn't matter if you're using a PC, a pair of tin cans, or a router, if the number of routes required to maintain connectivity doubles every 6 months, the cost of business for operating on the internet will be prohibitive for everyone except "the big players" you guys are spending your time smacking around. We would be more than happy to sell you a new box, or more certified memory every few months...hell, that sort of stupidity in the marketplace would give us more than enough business justification for high-priority projects. When CIDR was dreamed up, there were two problems it was trying to solve, routing and addressing. If you don't do heirarchical addressing at some places along your heirarchy, then you need to deal with the fact that (a) everyone has all routes (b) everyone is ANNOUNCING all routes (c) when a route flaps, it affects everyone If you router is non-expandable then bitch to your supplier, be they Cisco, Bay, the-guy-down-the-road-in-the-garage - anyone. I rarely see products that are capable of standing more than one or two doublings in CPU and memory capacity. They usually don't sell when they are produced because their initial investment cost is 3x the competition. BTW - I have not studied the RFC's - so what will IPv6 do for us in the contect of routeing aggregation and latger boxes etc ? It's a pity you haven't. IPv6 makes the addressing problem much less of an issue, but raised the number of routes in the internet from 2^32 to 2^128. The only sane way to deal with this is aggregation, AGAIN. So, the same pathetic fools who brought you CIDR are going to ruin your IPv6 dreams before they've started. I would ask that folks consider moving this OFF of the CIDR and NANOG mailing lists and onto com-priv where it is much more "on-topic." Paul
