If you were to upgrade the 6500 to a Sup720-3bxl or better, it would be a
far superior platform for handling multiple gigabit ethernet circuits and
full BGP than the NPE-G1. Sadly, the sup720 and required power supply and
fan card upgrades would cost more than that 7200/NPE-G1, but it'll route
considerably more traffic. I don't think you're going to get line-rate
GigE from the G1. You will with the 6500.
