The output shows that IGMP snooping is maintaining the router port in the multicast VLAN (VLAN 10)
and the member ports in the sub-VLANs (VLAN 2 through VLAN 5).
Port-based multicast VLAN configuration
Network requirements
• As shown in Figure 25 , Router A connects to a multicast source (Source) through GigabitEthernet
1/0/1, and to Switch A through GigabitEthernet 1/0/2. IGMPv2 runs on Router A. IGMPv2
Snooping runs on Switch A. Router A acts as the IGMP querier.
• The multicast source sends multicast data to multicast group 224.1.1.1. Host A, Host B, and Host C
are receivers of the multicast group, and the hosts belong to VLAN 2 through VLAN 4 respectively.
• Configure the port-based multicast VLAN feature on Switch A so that Router A just sends multicast
data to Switch A through the multicast VLAN and Switch A forwards the multicast data to the
receivers that belong to different user VLANs.
