The RSM is essentially an RSP-2 with an optional VIP2 attached.
It'll do full routes and as usual 128M means no problems, 64M may
work depending on the image, etc, but you'll be kinda exposed and
may end up losing some sleep.
Whether you want to use it that way vs. a dedicated router is
another question, there are horror stories floating around...
Probably safe if you want to multi-home your switch, probably
not a good idea if you want a multi-t3 bandwidth transit router
to also service your switch.
A point of irritation is that there's no OIR between the RSM
it's VIP and PA's, you want to change something and you have
to pull out the whole RSM (or power down the switch).
