3.6.4 Configuring MLD Report Suppression

When a Layer 2 device receives an MLD report from an IPv6 multicast group member,
the Layer 2 device forwards the message to the Layer 3 device directly connected with
it. Thus, when multiple members belonging to an IPv6 multicast group exist on the
Layer 2 device, the Layer 3 device directly connected with it will receive duplicate MLD
reports from these members.
With the MLD report suppression function enabled, within a query interval, the Layer 2
device forwards only the first MLD report of an IPv6 group to the Layer 3 device and will
not forward the subsequent MLD reports from the same multicast group to the Layer 3
device. This helps reduce the number of packets being transmitted over the network.
Follow these steps to configure MLD report suppression:
Enter system view
Enter MLD Snooping view
Enable MLD report

3.6.5 Configuring Maximum Multicast Groups that that Can Be Joined on a Port
By configuring the maximum number of IPv6 multicast groups that can be joined on a
port or a group of ports, you can limit the number of multicast programs available to
VOD users, thus to control the traffic on the port.
Follow these steps configure the maximum number of IPv6 multicast groups that can
be joined on a port or a group of ports:
Enter system view
Enter the
