Configuration procedure
1) Configure the IP address of each interface
Configure an IP address and subnet mask for each interface as per
configuration steps are omitted.
2) Configure Router A
# Enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP on
GigabitEthernet1/0/1.

[RouterA] multicast routing-enable
[RouterA] interface GigabitEthernet 1/0/1
[RouterA-GigabitEthernet1/0/1] igmp enable
[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> system-view
[SwitchA] igmp-snooping enable
Enable IGMP-Snooping ok.
# Create VLAN 100, assign GigabitEthernet1/0/1 through GigabitEthernet1/0/4 to this VLAN, and
enable IGMP Snooping in the VLAN.
[SwitchA] vlan 100
[SwitchA-vlan100] port GigabitEthernet 1/0/1 to GigabitEthernet 1/0/4
[SwitchA-vlan100] igmp-snooping enable
[SwitchA-vlan100] quit
