Network requirements
As shown in Figure 26:
• The network is a Layer 2-only network.
• Source 1 and Source 2 send multicast data to IPv6 multicast groups FF1E::101 and FF1E::102,
respectively.
• Host A and Host C are receivers of IPv6 multicast group FF1E::101, and Host B and Host D are
receivers of IPv6 multicast group FF1E::102.
• All receiver hosts run MLDv1 and all switches run MLDv1 snooping. Switch A (which is close to
the multicast sources) acts as the MLD snooping querier.
To prevent the switches from flooding unknown IPv6 packets in the VLAN, enable all the switches to
drop unknown IPv6 multicast packets.
