of 0 means that no hello messages are sent.
Usage guidelines
You can set the interval for sending hello messages in PIM view or interface view. The configurations
made in PIM view are effective on all interfaces, and the configurations made in interface view are
effective on only the current interface. If you set the interval in both PIM view and interface view, the
configuration in interface view always takes precedence.
