Configure the IP address and subnet mask for each interface as per
steps are omitted here.
Configure the OSPF protocol for interoperation among the switches in the PIM-DM domain. Ensure the
network-layer interoperation in the PIM-DM domain and enable dynamic update of routing information
among the switches through a unicast routing protocol. Detailed configuration steps are omitted here.
2) Enable IP multicast routing, and enable PIM-DM and IGMP
# Enable IP multicast routing on Switch A, enable PIM-DM on each interface, and enable IGMP on
VLAN-interface 100, which connects Switch A to the stub network.
<SwitchA> system-view
[SwitchA] multicast routing-enable
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] igmp enable
[SwitchA-Vlan-interface100] pim dm
[SwitchA-Vlan-interface100] quit
[SwitchA] interface vlan-interface 103
[SwitchA-Vlan-interface103] pim dm
[SwitchA-Vlan-interface103] quit
The configuration on Switch B and Switch C is similar to that on Switch A.
# Enable IP multicast routing on Switch D, and enable PIM-DM on each interface.
<SwitchD> system-view
[SwitchD] multicast routing-enable
[SwitchD] interface vlan-interface 300
[SwitchD-Vlan-interface300] pim dm
[SwitchD-Vlan-interface300] quit
[SwitchD] interface vlan-interface 103
[SwitchD-Vlan-interface103] pim dm
[SwitchD-Vlan-interface103] quit
[SwitchD] interface vlan-interface 101
[SwitchD-Vlan-interface101] pim dm
[SwitchD-Vlan-interface101] quit
[SwitchD] interface vlan-interface 102
[SwitchD-Vlan-interface102] pim dm
[SwitchD-Vlan-interface102] quit
3) Verify the configuration
Use the display pim interface command to view the PIM configuration and running status on each
interface. For example:
# View the PIM configuration information on Switch D.
[SwitchD] display pim interface
Interface
Vlan300
Vlan103
Vlan101
Vlan102
Carry out the display pim neighbor command to view the PIM neighboring relationships among the
switches. For example:
NbrCnt HelloInt DR-Pri
0 30 1
1 30 1
1 30 1
1 30 1
