Fig 17-1 PIM-DM Typical Environment
The configuration procedure for SwitchA and SwitchB is as follows:
(1) Configure SwitchA:
Switch (Config)#ip pim multicast-routing
Switch (Config)#interface vlan 1
Switch(Config-if-Vlan1)# ip address 10.1.1.1 255.255.255.0
Switch(Config-if-Vlan1)# ip pim dense-mode
Switch(Config-if-Vlan1)#exit
Switch (Config)#interface vlan2
Switch(Config-if-Vlan2)# ip address 12.1.1.1 255.255.255.0
Switch(Config-if-Vlan2)# ip pim dense-mode
(2) Configure SwitchB:
Switch (Config)#ip pim multicast-routing
Switch (Config)#interface vlan 1
Switch(Config-if-Vlan1)# ip address 12.1.1.2 255.255.255.0
Switch(Config-if-Vlan1)# ip pim dense-mode
Switch(Config-if-Vlan1)#exit
Switch (Config)#interface vlan 2
Switch(Config-if-Vlan2)# ip address 20.1.1.1 255.255.255.0
Switch(Config-if-Vlan2)# ip pim dense-mode
At the same time, you should pay attention to the configuration of Unicast
Routing Protocol, assure that each device can communicate with each other in the
network layer, and be able to implement dynamic routing update in virtue of Unicast
Routing Protocol.
17.2.5 PIM-DM Troubleshooting
In configuring and using PIM-DM Protocol, PIM-DM Protocol might not operate
normally caused by physical connection or incorrect configuration. Therefore, the user
