Devices in this topology are configured as follows:
 STG2 includes VLAN2; STG3 includes VLAN3.
 The multicast server sends IP multicast traffic for the following groups:
VLAN 2, 225.10.0.11 – 225.10.0.12, Source: 22.10.0.11

VLAN 2, 225.10.0.13 – 225.10.0.15, Source: 22.10.0.13

VLAN 3, 230.0.2.1 – 230.0.2.2, Source: 22.10.0.1

VLAN 3, 230.0.2.3 – 230.0.2.5, Source: 22.10.0.3

 The Mrouter sends IGMP Query packets in VLAN 2 and VLAN 3. The Mrouter's
IP address is 10.10.10.10.
The multicast hosts send the following IGMP Reports:
