7.1  Example for Configuring Basic IGMP Snooping
7.1.1  Network Requirements
Host B, Host C and Host D are in the same VLAN of the switch. All of them want to receive 
multicast streams sent to multicast group 225.1.1.1.
As shown in the following topology, Host B, Host C and Host D are connected to port 
1/0/1, port 1/0/2 and port 1/0/3 respectively. Port 1/0/4 is the router port connected to the 
multicast querier.
