Thanks for the quick reply.

So especially for v6 - since the kernel doesn't do IGMPv3 / MLDv2 - this
effectively downgrades all the bridge links to ASM then (at least with a
50% chance, i.e. when the kernel wins due to lower MAC-address), which
is a bit meh.

Now remaining question is, does the kernel detect if there is a
userspace-querier running on the same machine and silence itself then?
If not we probably need to address this as well somehow.


Cheers,

Steven
