• VOD streams are sent to receiver hosts in multicast. Receiver hosts of different organizations form
stub networks N1 and N2. Host A and Host C are multicast receiver hosts in N1 and N2,
respectively.
• MLDv1 runs between Router A and N1, and between the other two routers (Router B and Router C)
and N2.
• Router A acts as the MLD querier in N1. Router B acts as the MLD querier in N2 because it has a
lower IPv6 address.
Configure the routers to meet the following requirements:
• The hosts in N1 can only join the IPv6 multicast group FF1E::101.
• The hosts in N2 can join any IPv6 multicast groups.

Configuration procedure
1. Assign an IPv6 address and prefix length to each interface according to Figure 80. (Details not
shown.)
2. Configure OSPFv3 on the routers of the IPv6 PIM network to make sure the following conditions are
met: (Details not shown.)
{ The routers are interoperable at the network layer.
{ The routers can dynamically update their routing information.
3. Enable the IPv6 multicast routing, MLD, and IPv6 PIM-DM:
# On Router A, enable IPv6 multicast routing.
<RouterA> system-view
[RouterA] ipv6 multicast routing
[RouterA-mrib6] quit
# Enable MLD on GigabitEthernet 2/1/1.
[RouterA] interface gigabitethernet 2/1/1
