Oooh, you've got me there :-) My point was just that the additional state did not, as described, seem to me like such a massive amount more than that presently required. I thus doubted that lack of state capacity in switches would be a real (as distinct from a possible, likely or supposed) problem. If there *are* actual problems, then obviously I stand corrected. I don't mind being corrected, but I would be sad to see this aspect of IPv6 go by the board. I suspect that even if it *is* an actual problem now, it will turn out to be a transient one - switches will get more capacity and will just deal with it. Even if low-end switches don't, I expect that high-end switches will. But if it turns out that even the high end of the market doesn't care about traffic reduction but does want cheaper switches, then I guess we'll see a lot of non-MLD-snooping switches.
