Configuring Router A
# Enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP
on Ethernet 1/0/1.
<RouterA> system-view
[RouterA] multicast routing-enable
[RouterA] interface Ethernet 1/0/1
[RouterA-Ethernet1/0/1] igmp enable
[RouterA-Ethernet1/0/1] pim dm
[RouterA-Ethernet1/0/1] quit
[RouterA] interface Ethernet 1/0/2
[RouterA-Ethernet1/0/2] pim dm
[RouterA-Ethernet1/0/2] quit
Configuring Switch A
# Enable IGMP Snooping globally.
<SwitchA> system-view
[SwitchA] igmp-snooping enable
Enable IGMP-Snooping ok.
# Create VLAN 100, assign Ethernet 1/0/1 through Ethernet 1/0/4 to VLAN 100,
and enable IGMP Snooping in this VLAN.
[SwitchA] vlan 100
[SwitchA-vlan100] port Ethernet 1/0/1 to Ethernet 1/0/4
[SwitchA-vlan100] igmp-snooping enable
[SwitchA-vlan100] quit
Verifying the configuration
# View the multicast groups in VLAN 100 on Switch A.
<SwitchA> display igmp-snooping group vlan100
