6.1.1 Enable Multicast
Refer to “Common Multicast Configuration” of Chapter 2.
6.1.2 Enable PIM-DM
PIM-DM needs to be enabled in configuration of all interfaces.
After PIM-DM is enabled on an interface, it will send PIM Hello messages periodically
and process protocol packets sent by PIM neighbors.
Perform the following configuration in interface view.
Table 6-1 Enable PIM-DM
Operation Command
Enable PIM-DM on an interface
pim dm
Disable PIM-DM on an interface
undo pim dm
It’s recommended to configure PIM-DM on all interfaces in non-special cases. This
configuration is effective only after the multicast routing is enabled in system view.
Once enabled PIM-DM on an interface, PIM-SM cannot be enabled on the same
interface and vice versa.
6.1.3 Configure the Interface Hello Message Interval
After PIM is enabled on an interface, it will send Hello messages periodically on the
interface. The interval at which Hello messages are sent can be modified according to
the bandwidth and type of the network connected to the interface.
Perform the following configuration in interface view.
Table 6-2 Configure hello message interval on an interface
Operation Command
Configure the hello message interval on an
interface
pim timer hello seconds
Restore the interval to the default value
undo pim timer hello
The default interval is 30 seconds. You can configure the value according to different
network environments. Generally, this parameter does not need to be modified.
This configuration can be performed only after PIM (PIM-DM or PIM-SM) is enabled in
interface view.
