Port-Based Multicast Vlan Configuration Example - HP 6125G Configuration Manual

The output shows that 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 5).

Port-based multicast VLAN configuration example

Network requirements
As shown in
the IGMP querier. 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, and the hosts belong to VLAN 2 through VLAN 4
respectively.
Configure the port-based multicast VLAN feature on Switch A 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
Configure the IP address and subnet mask for each interface as per
