DES-7200 Configuration Guide Chapter 6 PIM-SM
Configuration
6-14
Suppose the devices are connected with the host correctly; IP addresses and
unicast routes are configured.
Example of PIM-SM networking diagram
Device Configuration
Take the device 1 as an example to show how to configure PIM-SM. The steps of
device 2, 3 and 4 are similar with device 1.
Step 1: Enable multicast routing
DES-7200# configure terminal
DES-7200(config)# ip multicast-routing
Step 2: Enable PIM-SM on the interface eth0
DES-7200(config)# interface eth 0
DES-7200(config-if)# ip pim sparse-mode
DES-7200(config-if)# end
Step 3: Configure the candidate BSR and candidate C-RP.
Set R2’s loopback1 to C-BSR and C-RP
DES-7200(config)# interface loopback 1
DES-7200(config-if)# ip address 100.1.1.1 255.255.255.0
DES-7200(config-if)# ip pim sparse-mode
DES-7200(config-if)# exit
DES-7200(config)# ip pim bsr-candidate loopback 1
DES-7200(config)# ip pim rp-candidate loopback 1
DES-7200(config-if)# end
