Hi Robin, I think I follow what you're saying. My answer is that the potentially millions or billions of folks who want/will want to multihome is one cause of the scaling problem, but it's not the root cause. The root cause is the described design defects in the protocols which prevent such multihoming from occurring in a resource-light manner. If the folks who want to multihome were the root cause of the problem then the solution would obviously be, "Tough luck." That would be precisely the opposite of productive, so that can't be the correct root cause. Regards, Bill Herrin -- William D. Herrin ................
