Basic MLD functions configuration example
Network requirements
As shown in Figure 89, receivers receive VOD information in the multicast mode. Receivers of different
organizations form stub networks N1 and N2, and Host A and Host C are multicast receivers in N1 and
N2 respectively.
MLDv1 runs between Switch A and N1. MLDv1 runs between the other two switches (Switch B and Switch
C) and N2. Switch B acts as the MLD querier because it has a lower IPv6 address.
The hosts in N1 can join only IPv6 multicast group FF1E::101, and the hosts in N2 can join any IPv6
multicast groups.

Configuration procedure
1. Enable IPv6 forwarding on each switch and configure an IP address and prefix length for each
interface as shown in Figure 89. (Details not shown.)
2. Configure OSPFv3 on the switches on the IPv6 PIM network to make sure the switches are
interoperable at the network layer and they can dynamically update their routing information.
(Details not shown.)
3. Enable the IPv6 multicast routing, MLD and IPv6 PIM-DM:
# Enable IPv6 multicast routing on Switch A, enable MLD on VLAN-interface 100, and enable IPv6
PIM-DM on each interface.
