How to forward multicast traffic to an external switch and still not to flood other virtual interfaces on the same bridge?

Solution Verified - Updated -

Issue

When the multicast traffic is generated on a virtual interface, other virtual interfaces that are part of the same bridge, are flooded by the multicast traffic even if they are not part of the same multicast group. Moreover all the multicast traffic has to be forwarded to an external switch configured as multicast router that is connected via eth0 interface.
