1.4.2 PIM-SM Configuration Example
Configuration requirements
The network topology is shown in Figure 36-7. Device 1 and the multicast source
locate in the same network, device 2 and receiver A locate in the same network.
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
Note that once PIM-SM is enabled, IGMP is enabled on various interfaces
automatically without manual configuration.
1.4.3 DVMRP Configuration Example
Configuration requirements
The network topology is shown in the following figure. Device 1 and the multicast
source locate in the same network, device 2 and receiver A locate in the same
network. Suppose the devices are connected with the host correctly; IP
addresses and unicast routes are configured.
