Good to know. I haven't done much with multicast yet, as the majority of
our (wireless) network hardware wouldn't support it. That has changed
some time this year, so I'll be looking forward to see, where it breaks
(or hopefully doesn't break).
I've not encountered a switch that broke ND yet. I guess there is a
first time for everything.
