Configuration procedure
The following configuration is based on the prerequisite that the devices are properly connected and all
the required IP addresses are already configured.
1) Configure Switch A:
# Set the interface IP address of VLAN 20 to 168.10.1.1 and enable PIM DM on the VLAN interface.
<SwitchA> system-view
[SwitchA] multicast routing-enable
[SwitchA] vlan 20
[SwitchA–vlan20]port GigabitEthernet 1/0/1
[SwitchA-vlan20] quit
[SwitchA] interface Vlan-interface 20
[SwitchA-Vlan-interface20] ip address 168.10.1.1 255.255.255.0
[SwitchA-Vlan-interface20] pim dm
[SwitchA-Vlan-interface20] quit
# Configure VLAN 10.
[SwitchA] vlan 10
[SwitchA-vlan10] quit
# Define GigabitEthernet 1/0/10 as a hybrid port, add the port to VLAN 10, and configure the port to
forward tagged packets for VLAN 10.
[SwitchA] interface GigabitEthernet 1/0/10
[SwitchA-GigabitEthernet1/0/10] port link-type hybrid
[SwitchA-GigabitEthernet1/0/10] port hybrid vlan 10 tagged
[SwitchA-GigabitEthernet1/0/10] quit
# Configure the interface IP address of VLAN 10 as 168.10.2.1, and enable PIM-DM and IGMP.
[SwitchA] interface Vlan-interface 10
[SwitchA-Vlan-interface10] ip address 168.10.2.1 255.255.255.0
[SwitchA-Vlan-interface10] igmp enable
2) Configure Switch B:
# Enable the IGMP Snooping feature on Switch B.
<SwitchB> system-view
[SwitchB] igmp-snooping enable
