I'm not a real expert in this stuff, so I'd appreciate it if someone  
would correct me if I have a misconception, but I thought that  
CSCdt34374 indicated that an Engine 2 card with input ACLs turned on  
would be limited to 171,000 routes in anything newer than  
12.0(13.5)S.  Since full views are in excess of 225,000 routes these  
days, wouldn't this foreclose using an E2?
