The output shows that GigabitEthernet 3/0/3 and GigabitEthernet 3/0/5 on Switch C have
become static member ports for IPv6 multicast group FF1E::101.

Network requirements
As shown in Figure 83 , in a Layer-2-only network environment, Source 1 sends IPv6 multicast data to the
multicast group FF1E::101, and Source 2 sends IPv6 multicast data to the multicast group FF1E::102. Host
A and Host C are receivers of multicast group FF1E::101, and Host B and Host D are receivers of multicast
group FF1E::102. MLDv1 runs on all the receivers and MLDv1 snooping runs on all the switches. Switch
A, which is close to the multicast sources, is chosen as the MLD snooping querier.
To prevent flooding of IPv6 unknown multicast traffic within the VLAN, be sure to configure all the
switches to drop IPv6 unknown multicast data packets.

Configuration procedure
1. Configure Switch A:
# Enable IPv6 forwarding and enable MLD snooping globally.
