Configuration Procedure Configuring IP addresses for the interfaces of each device

Configure the IP address and subnet mask for each interface as per Figure 36. The detailed configuration steps are omitted here.

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
