z 

As shown in 

, Router A connects to a multicast source (Source) through GigabitEthernet 

2/0/1, and to Switch A through GigabitEthernet 2/0/2.  

z 

IGMPv2 is required on Router A. IGMPv2 Snooping is required on Switch A. Router A acts as the 

IGMP querier.  

z 

Switch A’s GigabitEthernet 2/0/1 belongs to VLAN 10, GigabitEthernet 2/0/2 through 

GigabitEthernet 2/0/4 belong to VLAN 2 through VLAN 4 respectively, and Host A through Host C 

are attached to GigabitEthernet 2/0/2 through GigabitEthernet2/0/4 of Switch A respectively.  

z 

The multicast source sends multicast data to multicast group 224.1.1.1. Host A, Host B, and Host C 

are receivers of the multicast group.  

z 

Configure the port-based multicast VLAN feature so that Router A just sends multicast data to 

Switch A through the multicast VLAN and Switch A forwards the multicast data to the receivers that 

belong to different user VLANs.

1) Configure 

IP 

addresses 

Configure the IP address and subnet mask for each interface as per 

Figure 1-5.

 The detailed 

configuration steps are omitted here.  

2)  Configure Router A  

# Enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP on the host-side 

interface GigabitEthernet 2/0/2.
