Application Scenarios for MLD

Application Scenarios for MLD

MLD runs between member hosts and directly connected multicast routers to manage and maintain multicast group memberships. To forward multicast data from multicast sources to receivers, multicast routers must run IPv6 Protocol Independent Multicast (PIM) to set up forwarding paths. Figure 3-13 illustrates a typical MLD network topology.

The following solutions can be used in MLD applications.


Member Hosts

Interfaces Connected to Member Hosts

All Routers on the Network
