Configuration procedure
1) Configure IP addresses for interfaces
Configure an IP address and subnet mask for each interface as per
Figure 2-7. The configuration steps
are omitted here.
2) Configure Router A
# Enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP on GigabitEthernet
1/0/1.
<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 ports GigabitEthernet 1/0/1 through GigabitEthernet 1/0/4 to this VLAN, and
enable IGMP snooping and IGMP snooping proxying 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] igmp-snooping proxying enable
[SwitchA-vlan100] quit
