Port-based multicast VLAN configuration example
Network requirements
As shown in Figure 21:
• IGMPv2 runs on Switch A. IGMPv2 snooping runs on Switch B.
• Switch A acts as the IGMP querier.
• The multicast source sends multicast data to the multicast group 2 2 4 .1.1.1 . Host A, Host B, and Host
C are receivers. They belong to VLAN 2 through VLAN 4, respectively.
Configure a port-based multicast VLAN on Switch B to meet the following requirements:
• Switch A sends multicast data to Switch B through the multicast VLAN.
• Switch B forwards the multicast data to the receivers in different user VLANs.
