DES-7200 Configuration Guide Chapter 1 IPv4 Multicast
Configuration
1-9
Command Purpose
DES-7200 # debug nsm mcast vrf
Show the multicast operation on the
interface.
Execute the following command in the privileged configuration mode to show the
multicast statistics.
Command Purpose
DES-7200 # debug nsm mcast stats
Show the multicast statistics.
1.4 IPv4 Multicast Configuration Examples
1.4.1 PIM-DM Configuration Example
Configuration requirements
The network topology is shown in Figure 36-6. Device 1 and the multicast source
locate in the same network, device 2 and receiver A locate in the same network,
and device 3 and receiver B locate in the same network. Suppose the devices are
connected with the host correctly and the IP addresses are configured.
Example of PIM-DM networking diagram
Device Configuration
Take the device 1 as an example to show how to configure PIM-DM. The steps of
device 2 and 3 are similar with device 1.
Step 1: Enable multicast routing
DES-7200# configure terminal
DES-7200(config)# ip multicast-routing
Step 2: Enable PIM-DM on the interface eth0
DES-7200(config)# interface eth 0
DES-7200(config-if)# ip pim dense-mode
DES-7200(config-if)# exit
Step 3: Enable PIM-DM on the interface eth1 and return to the privileged user
mode.
DES-7200(config)# interface eth 1
DES-7200(config-if)# ip pim dense-mode
DES-7200(config-if)# end
The configuration of device 2 and 3 is similar to device 1.
