Enabling MLD report suppression

When a Layer 2 switch receives an MLD report from an IPv6 multicast group member, the Layer 2 switch
forwards the message to the Layer 3 device that directly connects to the Layer 2 switch. When multiple
members of an IPv6 multicast group are attached to the Layer 2 switch, the Layer 3 device might receive
duplicate MLD reports for the IPv6 multicast group from these members.
With the MLD report suppression function enabled, within a query interval, the Layer 2 switch forwards
only the first MLD report for the IPv6 multicast group to the Layer 3 device. It does not forward subsequent
MLD reports for the same IPv6 multicast group to the Layer 3 device. This helps reduce the number of
packets being transmitted over the network.
On an MLD snooping proxy, MLD reports for an IPv6 multicast group from downstream hosts are
suppressed if the forwarding entry for the multicast group exists on the proxy, whether the suppression
function is enabled or not.
To enable MLD report suppression:
Step
1. Enter system view.
2. Enter MLD-snooping view.
3. Enable MLD report
suppression.
Setting the maximum number of multicast groups that a port can
join
You can set the maximum number of IPv6 multicast groups that a port can join to regulate the traffic on
the port.
When you configure this maximum number, if the number of IPv6 multicast groups the port has joined
exceeds the configured maximum value, the system deletes all the forwarding entries for the port from the
