PIM Configuration Examples 595
# Enable IP multicast routing on Switch A, enable PIM-DM on each interface, and
enable IGMPv3 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] igmp version 3
[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 the configuration 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
Vpn-instance: public net
Interface NbrCnt HelloInt DR-Pri DR-Address
Vlan300 0 30 1 10.110.5.1
Vlan103 1 30 1 192.168.1.2
Vlan101 1 30 1 192.168.2.2
Vlan102 1 30 1 192.168.3.2
Carry out the display pim neighbor command to view the PIM neighboring
relationships among the switches. For example:
# View the PIM neighboring relationships on Switch D.
<SwitchD> display pim neighbor
Vpn-instance: public net
Total Number of Neighbors = 3
