Hi David,

http://bill.herrin.us/network/bgpcost.html

The source numbers change with time. Feel free to plug any realistic
source numbers into the formula that you please. The end result will
have the same impact: the cost is nontrivial.

If you want to challenge the methodology, I respectfully ask that you
find someone who does cost analysis for a living to assist you with
the particulars. I had a professional cost analyst review and validate
it. Same guy who got the V22 Osprey canceled before Congress put it
back.

If we do nothing, by what date do you expect IPv6 to exceed even 2% of
the total routing load?

I stand by my statement.

Bill Herrin
