10% by one measure. That is perhaps the most positive spin on what we can see. All that tells us is the AS view. To some extent netblocks, but that is really still based on origin AS also. It says nothing about which interfaces inside and behind an AS have PIM enabled and that is what really matters. I suspect real multicast reachability and deployment is quite a bit lower than 10%. I have no idea how to go about measuring it though, but 10% would have to be the best we could do if all hidden interfaces were enabed.
By any measure, multicast deployment is much larger than IPv6 deployment at present, and it is growing. I will be glad to argue the point to any length you might desire.
You know me Marshall, I care about multicast, but I'm not sure I'd go around comparing multicast to IPv6, that doesn't help. :-) John
