disagree that doing the split your way is probably better, I think it's a
moot point.  I strongly suspect these boxes will run out of RAM before
they're able to utilize another 256k routing slots with multiple full v4
tables.

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.
