According to this link, which alleges to be from cisco-nsp, an MSFC2 can 
hold 256,000 entries in its FIB of which 12,000 are reserved for 
Multicast. I do not know if the 12,000 can be set to serve the general 

The MSFC2 therefore can server 244,000 routes without uRPF turned on.

Any reasonably valid way of predicting when we'll hit 244,000 routes in 
the default-free zone?
