and process protocol packets sent by PIM neighbors.
Perform the following configuration in interface view.

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.

This configuration can be performed only after PIM (PIM-DM or PIM-SM) is enabled in
interface view.
