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:

Configuring Maximum Multicast Groups 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:
