Enabling MLD Proxying Optional
Configuring MLD Proxying
Configuring Multicast Forwarding on a
Downstream Interface
Optional
Configurations performed in MLD view are globally effective, while configurations performed in
interface view are effective on the current interface only.
If no configuration is performed in interface view, the global configurations performed in MLD view will
apply to that interface. Configurations performed in interface view take precedence over those
performed in MLD view.
Configuring Basic Functions of MLD
Configuration Prerequisites
Before configuring the basic functions of MLD, complete the following tasks:
z Configure any IPv6 unicast routing protocol so that all devices in the domain can be interoperable
at the network layer.
z Configure IPv6 PIM-DM or IPv6 PIM-SM.
In addition, prepare the following data:
z MLD version
z IPv6 multicast group address and IPv6 multicast source address for static group member
configuration
z ACL rule for IPv6 multicast group filtering
z The maximum number of IPv6 multicast groups that can be joined on an interface
Enabling MLD
Enable MLD on the interface on which IPv6 multicast group memberships are to be created and
maintained.
Follow these steps to enable MLD:
