Sub-VLAN-based multicast VLAN configuration example

Network requirements
As shown in
IGMPv2 runs on Layer 3 device Switch A, and IGMPv2 snooping runs on Layer 2 device Switch B.
•
Switch A acts as the IGMP querier.
•
The multicast source sends multicast data to the multicast group 224.1.1.1. Host A, Host B, and Host
•
C are receivers. They belong to VLAN 2 through VLAN 4, respectively.
Configure a sub-VLAN-based multicast VLAN on Switch B to meet the following requirements:
Switch A sends the multicast data to Switch B through the multicast VLAN.
•
• Switch B forwards the multicast data to the receivers in different user VLANs.
