IGMP Snooping Configuration Examples

Configuring Group Policy and Simulated Joining

Network requirements
As shown in
and to Switch A through GigabitEthernet 1/0/1.
IGMPv2 is required on Router A, IGMP Snooping version 2 is required on Switch A, and Router A
will act as the IGMP querier on the subnet.
It is required that the receivers, Host A and Host B, attached to Switch A can receive multicast
traffic addressed to multicast group 224.1.1.1 only.
It is required that 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.

Configuration procedure
1) Configure IP addresses
Configure an IP address and subnet mask for each interface as per
configuration steps are omitted.
2) Configure Router A
# Enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP on GigabitEthernet
1/0/1.
