sorry, address typo. again.
IMHO, a better place for this discussion than homenet is Mboned,
for example in conjunction with evolving
draft-mcbride-mboned-wifi-mcast-problem-statement.
I do not particularily like the scope either of the discussion in homenet
or in the draft in MBoned, because
Hmm... the multicast to unicast conversion described in there looks fairly
weak. It doesn't discuss any problems with IGMPv2/MLDv1 wrt to report
suppression and how to deal with that for example. Or the challenge that
hosts may not be happy about receiving IP multicast packets with unicast MAC

To come back on the discussion why mcast matters for IPv6 while bcast does
not for IPv4:
- IPv6 uses heavily mcast while in IPv4 (ND is quite chatty)
- IPv6 uses many more addresses than IPv4 (hence even more chatty)
A couple of us running very large (more than 1 STA) WiFi network have

From what I heard in v6ops, it doesn't work well for larger settings like
conferences, at least not without multicast reduction techniques.
So I'd say it suffers from the exact
I don't see how you can claim that ISIS can't use multicast on wifi
because multicast on wifi doesn't work,
I have never claimed that. Babel uses multicast on wifi. (Once again,
Mikael, I request that you stop misrepresenting my position.)
I think that the multicast reduction technique used
However, I do think that 802.11 needs to point out to its members that if
they don't implement assured multicast replication, IP doesn't work
properly.
That's an overstatement. IPv6 works just fine over 802.11, it just
suffers from increased multicast packet loss and lower rate. I don't
HGI is requesting Home Gateways to perform Wi-Fi multicast-to-unicast
conversion, see http://www.homegatewayinitiative.org/publis/P_HGI01628R19.pdf .
