Typical MLD Application

Typical MLD Application

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 Protocol Independent Multicast (PIM) IPv6 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

Hosts dynamically join multicast groups through ASM.

Enable MLDv1 or MLDv2.

Enable MLDv1 or MLDv2.

Enable PIM-DM (IPv6) or PIM-SM (IPv6).

Hosts dynamically join multicast groups through SSM.

Enable MLDv2.

Enable MLDv2.

Enable PIM-SM (IPv6).

Hosts dynamically join multicast groups through SSM mapping.

Enable MLDv1.

Enable MLDv2, enable MLD SSM mapping, and configure source-group mapping.

Enable PIM-SM (IPv6).
