[c-nsp] Sup720 vs RSP720 - Difference?

[Rick Ernst]

Thanks to everyone for the feedback so far.

For my situation, the two biggest items that stand out are:
 - 4GB vs 1GB RAM
 - 7600 chassis only, not 6500 (planning on a 7600 chassis, though)

I'm a bit surprised that you are seeing ~60%  memory used by BGP. My
border routers (4 routers, 1 full feed each) and core (route-reflectors)
are both only showing about 25% memory used, total.

Since the Sup720 (spec-wise, at least) capacity is roughly 2 orders of
magnitude higher than I'm currently pushing through the core, it looks
like it should serve for several years.  The RSP720 becomes an upgrade
option if 1GB is no longer big enough for full tables (plus IPv6
roll-out?).

On the subject of memory and DFCs... do the DFCs also support 4GB for the
FIB, or is this an apples vs oranges comparison?

Thanks,
