As shown above, 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 4).
Port-Based Multicast VLAN Configuration
Network requirements
z
As shown in Figure 1-5 , Router A connects to a multicast source (Source) through GigabitEthernet
1/0/1, and to Switch A through GigabitEthernet 1/0/2.
z
IGMPv2 is required on Router A. IGMPv2 Snooping is required on Switch A. Router A acts as the
IGMP querier.
z
Switch A’s GigabitEthernet 1/0/1 belongs to VLAN 10, GigabitEthernet 1/0/2 through
GigabitEthernet 1/0/4 belong to VLAN 2 through VLAN 4 respectively, and Host A through Host C
are attached to GigabitEthernet 1/0/2 through GigabitEthernet1/0/4 of Switch A respectively.
z
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.
z
Configure the port-based multicast VLAN feature 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.
