  • The Linux kernel doesn't forward link local groups, such as FF01:: and FF02, see also RFC 4291. So multicast groups should look like FF05:: or FF15::.
  • The mcproxy doesn't support MLDv2 at the moment. If a multicast listener subscribes to a group (normally with a MLDv2 Report) then the mcproxy cannot process this report. So the mcproxy doesn't notice the listener until the mcproxy sends a MLDv1 Query and the listener has to answer with an MLDv1 Report. If the MLD version of the listener is set to MLDv1, this delay can be avoided. This can be done with the following command:
 echo 1 > /proc/sys/net/ipv6/conf/<inerface>/force_mld_version

The upstream of the mcproxy has the same problem.
