• MLDv2 runs on Switch D’s VLAN-interface 400. The receiver host runs MLDv1, and does not
support MLDv2. Therefore, the Receiver host cannot specify expected multicast sources in its
membership reports.
• Source 1, Source 2, and Source 3 send IPv6 multicast packets to multicast groups in the IPv6 SSM
group range. You can configure the MLD SSM mapping feature on Switch D so that the receiver host
will receive IPv6 multicast data from Source 1 and Source 3 only.

Configuration procedure
1. Enable IPv6 forwarding and configure IPv6 addresses and IPv6 unicast routing
Enable IPv6 forwarding on each switch and configure an IPv6 address and prefix length for each
interface as shown in Figure 90 . (details not shown)
Configure OSPFv3 for interoperability among the switches. Ensure the network-layer interoperation on
the IPv6 PIM-SM domain and dynamic update of routing information among the switches through an
IPv6 unicast routing protocol. (details not shown)
2. Enable IPv6 multicast routing, enable IPv6 PIM-SM on each interface and enable MLD and MLD
SSM mapping on the host-side interface.
# Enable IPv6 multicast routing on Switch D, enable IPv6 PIM-SM on each interface, and enable MLD
(version 2) and MLD SSM mapping on VLAN-interface 400.
