MLDv1 is required between Router A and N1. MLDv2 is required between the
■
other two routers (Router B and Router C) and N2, with Router B as the MLD
querier.

Configuration procedure
1 Configure IPv6 addresses for the router interfaces and an IPv6 unicast protocol
Configure an IPv6 address and prefix length for each interface as shown in
Figure 357. The detailed configuration steps are not discussed in this document.
Configure OSPFv3 for interoperation between the routers. Ensure the
network-layer interoperation between Router A, Router B, and Router C on the
IPv6 PIM network and dynamic update of routing information between the routers
through a unicast routing protocol. The detailed configuration steps are omitted
here.
2 Enable the IPv6 multicast routing and enable MLD on the host interfaces.
# Enable IPv6 multicast routing on Router A, enable MLD and IPv6 PIM-DM on
Ethernet1/0, and set the MLD version number to 1.
