2.2.11 Configuring a Port as a Simulated Group Member

Generally, hosts running IGMP respond to the IGMP query messages of the multicast
switch. If hosts fail to respond for some reason, the multicast switch 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 switch as a
multicast group member. When the port receives IGMP query messages, the multicast
switch 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:
When an Ethernet port is configured as a simulated member host, the switch
sends an IGMP report through this port. Meanwhile, the switch sends the same
IGMP report to itself and establishes a corresponding IGMP entry based on this
report.
When receiving an IGMP general query, the simulated host responds with an
IGMP report. Meanwhile, the switch sends the same IGMP report to itself to
ensure that the IGMP entry does not age out.
When 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.
