Multicast VLAN configuration examples
Port-based multicast VLAN configuration
Network requirements
• As shown in Figure 20 , Router A connects to a multicast source—Source—through Ethernet1/0/1,
and to Switch A through Ethernet1/0/2.
• IGMPv2 is required on Router A. IGMPv2 snooping is required on Switch A. Router A acts as the
IGMP querier.
• Switch A’s Ethernet1/0/1 belongs to VLAN 10, Ethernet1/0/2 through Ethernet1/0/4 belong to
VLAN 2 through VLAN 4 respectively, and Host A through Host C are attached to Ethernet1/0/2
through Ethernet1/0/4 of Switch A respectively.
• 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.
• 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.

Configuration procedure
1. Configure IP addresses
Configure the IP address and subnet mask for each interface according to Figure 20 . The detailed
configuration steps are omitted here.
2. Configure Router A
# Enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP on the host-side
interface Ethernet1/0/2.
