IGMP snooping configuration examples

Group policy and simulated joining configuration example
Network requirements
As shown in
snooping.
Configure a group policy and simulated joining to meet the following requirements:
•
Host A and Host B receive only the multicast data addressed to multicast group 224.1.1.1.
Multicast data can be forwarded through GigabitEthernet 1/0/3 and GigabitEthernet 1/0/4 of
Switch A uninterruptedly, even though Host A and Host B fail to receive the multicast data.
•
Switch A will drop unknown multicast data instead of flooding it in VLAN 100.
