Multicast VLAN configuration examples

Sub-VLAN-based multicast VLAN configuration

Network requirements

• Router A connects to a multicast source through GigabitEthernet 1/0/1 and to Switch A, through

GigabitEthernet 1/0/2.

• IGMPv2 runs on Router A, and IGMPv2 snooping runs on Switch A. Router A is the IGMP querier.

• 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 GigabitEthernet 1/0/4 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 sub-VLAN-based multicast VLAN feature so that Router A just sends multicast data to

Switch A through the multicast VLAN and Switch A forwards the traffic to the receivers that belong

to different user VLANs.
