IGMP snooping configuration examples
This section provides examples of configuring IGMP snooping.

Network requirements
An MSR with a fixed Layer 2 Ethernet switching interface or a Layer 2 switching interface module acts as
a switch (Switch A in Figure 46).
As shown in Figure 46, I
GMPv2 runs on Router A, IGMPv2 snooping runs on Switch A, and Router A acts
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 Ethernet 1/3 and Ethernet 1/4 of Switch A
even if Host A and Host B accidentally, temporarily stop receiving multicast data. Switch A drops
unknown multicast data and does not broadcast the data to the VLAN where Switch A resides.

Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 46. (Details not
shown.)
