Multicast traffic we=E2=80=99re subscribed to will n= ot arrive unless our address is assigned to the bridge rather than the me= mber interfaces. You mostly get away with that for IPv4 (which is often w= orse, because =E2=80=9CEverything works except for X=E2=80=9D), but it to= tally breaks IPv6.

That=E2=80=99s a secondary consideration, but ni= ce to have anyway. =E2=80=94 Kristof
