Configuration procedure
1. Configure an IP address and subnet mask for each interface as per Figure 14. (Details not shown.)
2. On Router A, enable IP multicast routing, enable IGMP on GigabitEthernet 1/0/1, and enable
PIM-DM on each interface.
<RouterA> system-view
[RouterA] multicast routing-enable
[RouterA] interface gigabitethernet 1/0/1
[RouterA-GigabitEthernet1/0/1] igmp enable
[RouterA-GigabitEthernet1/0/1] pim dm
[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
[SwitchA-igmp-snooping] quit
# Create VLAN 100, assign GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3 to this VLAN,
and enable IGMP snooping in the VLAN.
[SwitchA] vlan 100
[SwitchA-vlan100] port gigabitethernet 1/0/1 to gigabitethernet 1/0/3
[SwitchA-vlan100] igmp-snooping enable
[SwitchA-vlan100] quit
# Configure GigabitEthernet 1/0/3 to be a static router port.
[SwitchA] interface gigabitethernet 1/0/3
