to a certain extent that depends on what software you're using.  12.x seems
to be a good bit more memory efficient than 15.x on the sup720.  Otherwise
yeah, RP memory is the next critical limiting factor on these boxes,
assuming if you can live with the crippling convergence times with large
numbers of prefixes.
