The memory limit shouldn't be a problem for a while unless you have lots
of peers. We run RSP4's with 256MB and two full BGP views and only use
around 150-160MB.

I would think anything RSP4/8/16 should be fine if your VIPs are up to the
task. The RSP8 and RSP16 can switch more than the RSP4, although I'm not
sure how much impact the difference would have since with normal packet
sizes <100 Mb/s is not going to stress any of those RSPs. For minimum size
packets or DoS stuff a 75xx is going to have problems no matter what you
do.
