• 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 Switch A and N1, and between the other two switches (Switch B and Switch
C) and N2.
• Switch A acts as the MLD querier in N1. Switch B acts as the MLD querier in N2 because it has a
lower IPv6 address.
Configure the switches to achieve the following goals:
• The hosts in N1 can join only 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 as shown in Figure 43 . (Details not
shown.)
2. Configure OSPFv3 between the switches to make sure the following conditions are met: (Details
not shown.)
{
The switches are interoperable at the network layer.
{
The switches can dynamically update their routing information.
3. Enable the IPv6 multicast routing, MLD, and IPv6 PIM-DM:
# On Switch A, enable IPv6 multicast routing globally.
system-view
[SwitchA] ipv6 multicast routing
[SwitchA-mrib6] quit
# Enable MLD on VLAN-interface 100 (the interface that connects to the stub network).
[SwitchA] interface vlan-interface 100
