The output shows that GigabitEthernet 2/1/3 and GigabitEthernet 2/1/5 on Switch C have become
static member ports of the multicast group 224.1.1.1.

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 224.1.1.1 and 225.1.1.1,
•
respectively.
•
Host A and Host C are receivers of multicast group 224.1.1.1, and Host B and Host D are receivers
of multicast group 225.1.1.1.
All host receivers run IGMPv2, and all switches run IGMPv2 snooping. Switch A (which is close to
•
the multicast sources) acts as the IGMP querier.
To prevent the switches from flooding unknown packets in the VLAN, enable dropping unknown multicast
packets on all the switches.
