==== Topology

image::topology.svg[IGMP VLAN topology, align=center, scaledwidth=75%]

==== Sequence

. Set up topology and attach to target DUT
. Configure device
. Start multicast senders on host:data11, group 224.2.2.2, and host:data22, group 224.1.1.1
. Verify group 224.2.2.2 is flooded to host:data21
. Verify group 224.1.1.1 is flooded to host:data12
. Verify group 224.2.2.2 on host:data11, 224.1.1.1 on host:data21, 224.2.2.2 on host:data12 and 224.1.1.1 on host:data22 is not received
. Join multicast group 224.2.2.2 on host:data21
. Verify group 224.2.2.2 on host:data11, 224.1.1.1 on host:data21, 224.2.2.2 on host:data12 and 224.1.1.1 on host:data22 is not received
. Verify group 224.2.2.2 is forwarded to host:data21
. Verify group 224.1.1.1 is forwarded to host:data12
