[RouterA-Ethernet1/1] igmp enable

[RouterA-Ethernet1/1] pim dm

[RouterA-Ethernet1/1] quit

[RouterA] interface ethernet 1/2

[RouterA-Ethernet1/2] pim dm

[RouterA-Ethernet1/2] quit

3. Configure Switch A:

# Enable IGMP snooping globally.

<SwitchA> system-view

[SwitchA] igmp-snooping

[SwitchA-igmp-snooping] quit

# Create VLAN 100, assign Ethernet 1/1 through Ethernet 1/3 to the VLAN, and enable IGMP

snooping for the VLAN.

[SwitchA] vlan 100

[SwitchA-vlan100] port ethernet 1/1 to ethernet 1/3

[SwitchA-vlan100] igmp-snooping enable

[SwitchA-vlan100] quit

# Configure Ethernet 1/3 as a static router port.
