Configuring a Port as a Simulated Group Member

Generally, hosts running IGMP respond to the IGMP query messages of the multicast device. If hosts fail to respond for some reason, the multicast device may consider that there is no member of the multicast group on the local subnet and remove the corresponding path.

To avoid this from happening, you can configure a port of the VLAN of the device as a multicast group member. When the port receives IGMP query messages, the multicast device will respond. As a result, the port of the VLAN can continue to receive multicast traffic.

Through this configuration, the following functions can be implemented:

zWhen an Ethernet port is configured as a simulated member host, the device sends an IGMP report through this port. Meanwhile, the device sends the same IGMP report to itself and establishes a corresponding IGMP entry based on this report.

zWhen receiving an IGMP general query, the simulated host responds with an IGMP report. Meanwhile, the device sends the same IGMP report to itself to ensure that the IGMP entry does not age out.

zWhen the simulated joining function is disabled on an Ethernet port, the simulated host sends an IGMP leave message.

Therefore, to ensure that IGMP entries will not age out, the port must receive IGMP general queries periodically.
