If you turn off uRPF, then you can get ~240k IPv4 routes. If you 
leave it enabled, you can only get 140k IPv4 routes.

Like you said, it may be required. With the CAC-2500W power supplies 
running on 120V, you can power a Sup720-3BXL and FAN2 and 3-4 low 
power cards. If you plan to have redundant Sups, then you must have 
208V or you will be over your power budget for the de-rated 1250W 
supply rating.
