1. Configure IP addresses for interfaces
Configure an IP address and subnet mask for each interface as per Figure 17 . (details not shown)
2. Configure Router A
# Enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP on GigabitEthernet
1/0/1.
system-view
[RouterA] multicast routing-enable
[RouterA] interface gigabitethernet 1/0/1
[RouterA-GigabitEthernet1/0/1] igmp enable
[RouterA-GigabitEthernet1/0/1] pim dm
[RouterA-GigabitEthernet1/0/1] quit
[RouterA] interface gigabitethernet 1/0/2
[RouterA-GigabitEthernet1/0/2] pim dm
[RouterA-GigabitEthernet1/0/2] quit
3. Configure Switch A
# Enable IGMP snooping globally.

[SwitchA-igmp-snooping] quit
# Create VLAN 100, assign ports GigabitEthernet 1/0/1 through GigabitEthernet 1/0/4 to this VLAN,
and enable IGMP snooping and IGMP snooping proxying in the VLAN.
[SwitchA] vlan 100
[SwitchA-vlan100] port gigabitethernet 1/0/1 to gigabitethernet 1/0/4
