[c-nsp] bgp router

[Rossella Mariotti-Jones]

This is good to know, thanks.
We're going to have at least two ISPs possibly add more in the future,
and a 100Mb pipe to it, which will grow to 200Mb soon. Right now we only
have a DS3 and a lot of the times it gets up to 40Mb. I'm assuming we'll
probably be pushing 80Mb easily pretty soon. This is our first BGP
experience, we don't want to over buy but we also don't want to get
stuck with a unit that's not going to be able to keep up.

7600 and 2800 series are very different beasts.  Figure out what sort of

throughput/backplane capacity you need and that should point you towards

the apropriate platform.  If you go 7600, don't buy less than the 
sup720-3bxl.  The older sup720-3b, regardless of how much RAM you put on

it, won't properly handle full routes.
