too many routes

This is what I beleave sprint is doing. They are using the new Cisco 12000
GSR with external router servers. It is a smart way of patching the
problem. If you need more CPU or memory you can just add a bigger box and
more RAM.

Sprintlink does not use route-servers today, the RP in the GSR is
probably enough for a while, right now it's not very busy.

After convergence the CPU in any distributed switching
framework should be a function of the routing algorithms
and the amount of background noise.

However, to close off the nit-pick, the RP in the GSR
seems to perform spectacularly well even under unusually
heavy routing load.

This is great as long as there is no need to replace the
RP before a replacement is technologically feasible...
