The Sup720-3BXL is rated at 1M routes (TCAM for forwarding) and comes with 
one gig of memory and a 600Mhz CPU. We looked at SPF calculations for ISIS 
and it does SPF at times roughly in between a GRP-B and an PRP-2.

So my guess is that it will take a lot of BGP views (with 2 full views we 
have 750 meg free memory).
