IGMP snooping configuration examples

Group policy and simulated joining configuration example

Network requirements
As shown in
as the IGMP querier on the subnet.
The receivers, Host A and Host B, can receive multicast traffic addressed to multicast group 224.1.1.1 only.
Multicast data for group 224.1.1.1 can be forwarded through GigabitEthernet 1/0/3 and
GigabitEthernet 1/0/4 of Switch A even if Host A and Host B accidentally, temporarily stop receiving
multicast data, and that Switch A drops unknown multicast data and does not broadcast the data to the
VLAN where Switch A resides.

Configuration procedure
Configure an IP address and subnet mask for each interface as per
1.
On Router A, enable IP multicast routing, enable IGMP on GigabitEthernet 1/0/1, and enable
