port. Multicast router knows which multicast groups exist on which interface
dynamically.
Compatible mode
If we select the dynamic mode in MVR setting, IGMP report message transmitted
from the receiver port will not be transmitted to a multicast router. Multicast router
must be statically configured.

Operation Mode

Join Operation
A subscriber sends an IGMP report message to the switch to join the appropriate
multicast. It tests whether the IGMP report matches the switch configured
multicast MAC address. If matches, the switch CPU modifies the hardware
address table to include this receiver port and VLAN as a forwarding destination
of the MVLAN
Leave Operation
Subscriber sends an IGMP leave message to the switch to leave the multicast.
The switch CPU sends an IGMP group-specific query through the receiver port
VLAN. If there is another subscriber in the VLAN, subscriber must respond within
the max response time. If there is no subscriber, the switch eliminates this
receiver port.
Immediate Leave Operation
Subscriber sends an IGMP leave message to the switch to leave the multicast.
Subscribers do not need to wait for the switch CPU to send an IGMP
group-specific query through the receiver port VLAN. The switch will immediately
eliminate this receiver port.

Scenario of MVR

In the following section, we will provide an example to illustrate how to configure
MVR. In this scenario, the main job of media server is to transmit the media
stream via port 10 to GS-4024. The multicast traffic flowing into the GS-4024 will
be tagged with PVID=100. In the VES-1616F-3X, we enable the MVR function to
allocate the multicast traffic from GS-4024 to separate VLAN hosts.
