5. Configure Router D in the same way as you configure Router C. (Details not shown.)
6. 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 1/0/4 to this VLAN,
and enable IGMP snooping and PIM snooping in the VLAN.
[SwitchA] vlan 100
[SwitchA-vlan100] port gigabitethernet 1/0/1 to gigabitethernet 1/0/4
[SwitchA-vlan100] igmp-snooping enable
[SwitchA-vlan100] pim-snooping enable
[SwitchA-vlan100] quit
Verifying the configuration
# On Switch A, display the PIM snooping neighbor information of VLAN 100.
[SwitchA] display pim-snooping neighbor vlan 100
Total number of neighbors: 4
VLAN ID: 100
Total number of neighbors: 4
