7.2  Example for Configuring MVR
7.2.1  Network Requirements
Host B, Host C and Host D are in three different VLANs of the switch. All of them want to 
receive multicast streams sent to multicast group 225.1.1.1.
7.2.2  Network Topology
As shown in the following network 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 1/0/1, port 1/0/2 and port 1/0/3 
belong to VLAN 10, VLAN 20 and VLAN 30 respectively. Port 1/0/4 is connected to the 
multicast network in the upper layer network.
