MLD Snooping Configuration Examples
Configuring IPv6 Group Policy and Simulated Joining
Network requirements
z As shown in Figure 1-3, Router A connects to the IPv6 multicast source through GigabitEthernet
1/0/2 and to Switch A through GigabitEthernet 1/0/1. Router A is the MLD querier on the subnet.
z MLDv1 is required on Router A, MLD Snooping version 1 is required on Switch A, and Router A will
act as the MLD querier on the subnet.
z It is required that the receivers, Host A and Host B, attached to Switch A can receive IPv6 multicast
traffic addressed to IPv6 multicast group FF1E::101 only.
z It is required that IPv6 multicast data for group FF1E::101 can be forwarded through
GigabitEthernet 1/0/3 and GigabitEthernet 1/0/4 of Switch A even if Host A and Host B accidentally,
temporarily stop receiving IPv6 multicast data.

Configuration procedure
1) Enable IPv6 forwarding and configure IPv6 addresses
Enable IPv6 forwarding and configure an IPv6 address and prefix length for each interface as per
Figure 1-3. The detailed configuration steps are omitted.
2) Configure Router A
# Enable IPv6 multicast routing, enable IPv6 PIM-DM on each interface, and enable MLDv1 on
GigabitEthernet 1/0/1.
