Speaking of which, does Ascend have SNMP working on their boxes yet? Can you still crash them by portscanning them?

Provided you think that they can do it. I think that a more reasonable approach is that presented at http://www.pluris.com
There's a whole bunch of people out there throwing vaporware promises around about "solving" the routing table problem, in the hopes that enough industry momentum behind them will give them enough time and money to "solve" the problem. This is a fundamentally hard problem, born not of Unix architecture (notice that it is IOS which is having the problem) nor of insistence on using "stock" hardware (there's enough specialized hardware in your average cisco7k to power the space shuttle.)
This is a _fundamentally_ hard problem, and no one, at least that I have seen, has a solution. "hardware assisted route table lookups" may be interesting, but I for one have not seen Patricia trees implemented in hardware.
I'll believe one of these promises when I see it work. Until then, I'd rather work on making sure that Linux copes as well as possible with these challenges.
