10.7 Configuration MLD Limit Function
If you want to restrict the servable IPTV ICPs and the number of access users on an IP core
network, the MLD limit function is required. Configuring the MLD limit function involves
setting the maximum number of global MLD group memberships, maximum number of global
MLD group memberships in a single instance, and maximum number of MLD group
memberships on an interface.
