As shown above, GigabitEthernet 2/0/3 and GigabitEthernet 2/0/5 on Switch C have become static 

member ports for IPv6 multicast group FF1E::101. 

z 

As shown in 

, in a Layer-2-only network environment, two multicast sources Source 1 

and Source 2 send IPv6 multicast data to multicast groups FF1E::101 and FF1E::102 respectively, 

Host A and Host C are receivers of multicast group FF1E::101, while Host B and Host D are 

receivers of multicast group FF1E::102. 

z 

MLDv1 is enabled on all the receivers and MLDv1 Snooping is enabled on all the switches. Switch 

A, which is close to the multicast sources, is chosen as the MLD snooping querier. 

z 

To prevent flooding of unknown multicast traffic within the VLAN, it is required to configure all the 

switches to drop unknown multicast data packets.
