==== Test sequence
. Set up topology and attach to target DUTs
. Configure device
. Start multicast sender on host:data0, group 224.1.1.1
. Verify that the group 224.1.1.1 is flooded on host:data2 and host:data3
. Join multicast group 224.1.1.1 on host:data2
. Verify group 224.1.1.1 is received on host:data2
. Verify that the group 224.1.1.1 is no longer received on host:data3
