Configuration procedure
1. Configure an IP address and subnet mask for each interface as shown in Figure 14 . (Details not
shown.)
2. On Router A, enable IP multicast routing, enable PIM-DM on each Layer 3 interface, and enable
IGMP on GigabitEthernet 3/0/1.
<RouterA> system-view
[RouterA] multicast routing-enable
[RouterA] interface GigabitEthernet 3/0/1
[RouterA-GigabitEthernet3/0/1]port link-mode route
[RouterA-GigabitEthernet3/0/1] igmp enable
[RouterA-GigabitEthernet3/0/1] pim dm
[RouterA-GigabitEthernet3/0/1] quit
[RouterA] interface GigabitEthernet 3/0/2
[RouterA-GigabitEthernet3/0/2]port link-mode route
[RouterA-GigabitEthernet3/0/2] pim dm
[RouterA-GigabitEthernet3/0/2] quit
3. Configure Device A:
# Enable IGMP snooping globally.
<DeviceA> system-view
[DeviceA] igmp-snooping
[DeviceA-igmp-snooping] quit
# Create VLAN 100, assign GigabitEthernet 3/0/1 through GigabitEthernet 3/0/4 to this VLAN,
and enable IGMP snooping and the function of dropping unknown multicast traffic in the VLAN.
[DeviceA] vlan 100
[DeviceA-vlan100] port GigabitEthernet 3/0/1 to GigabitEthernet 3/0/4
[DeviceA-vlan100] igmp-snooping enable
[DeviceA-vlan100] igmp-snooping drop-unknown
[DeviceA-vlan100] quit
