The cost per prefix per router is obviously only measured in cents per year. You do know that Cisco's sales are north of $20B per year, right? Juniper, which sells few products that aren't DFZ routers, also posts annual revenues well north of $1B. > Feel free to explain how confused I am.

I encourage you to critique the numbers and then add them up for yourself. Regards, Bill Herrin -- William D.
