Well, a modern switch should work fine, even if not directly
Wouldn't the multicast flooding be just like broadcasts tho? Some of
my sites don't have switches that will be upgraded or upgradeable to
software that will support IPv6 directly (at least not for a few
years). Is that going to cause major headaches? I under stand the RA
risks but the DHCPv6

Are there any
yes

Hi Iljitsch,
The switches from Extreme Networks do MLD and MLD snooping, I know for sure on
the x450's and up, probably below that line as well.

Cisco has had MLD snooping support for some time. But they seem to
have broken it in a recent release, so it drops ND traffic and breaks
IPv6; been after them to fix it, but doesn't look like it's been
resolved yet.
But you're correct that without MLD snooping IPv6 ND traffic is on par
with IPv4
Iljitsch,

Something as enterprisey as even HP Procurve (!) has been doing this for years.

however, that a large IPv6 multicast stream, like video or system
imaging, would be about as bad as doing so on

Well, that's another problem.
To make a long story short, the network (not mine and I don't have any kind of
control over that either) that my customers (including me) are using, did put
in new equipment (a switch) over a year ago and after that I lost my IPv6
connection that I had previously.
Dumb question.. what does the switch (L2) have to do with IPv6 (L3), or
is it one of those 'somewhere in between the two' things?

We've also encountered old IOSes that didn't forward Ethernet frames
that contained IPv6 payload.
