All we use them for is IPv4 routing and BGP.  Nothing else.  Very few local 
routes also.

Sounds like we'll need the RE-850 if we want to take more than our 2 full feeds 
though -- although others have said we may run out of CFEB RAM first?  Excuse 
the newbie question, but what is the CFEB RAM used for -- we have one router 
with one full feed and the CFEB is at 42% RAM, another with two full feeds and 
the CFEB is at 42% also...
