The output shows that Ten-GigabitEthernet 1/0/3 on Switch A has become a static router port.

The output shows that Ten-GigabitEthernet 1/0/3 and Ten-GigabitEthernet 1/0/5 on Switch C have
become static member ports of the IPv6 multicast group FF1E::101.

Network requirements
As shown in
The network is a Layer 2-only network.
•
Source 1 and Source 2 send multicast data to the multicast groups FF1E::101 and FF1E::102,
•
respectively.
•
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.
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 dropping unknown
IPv6 multicast packets on all switches.
