this section:
• In PIM view, the configuration takes effect on all interfaces. In interface view, the configuration takes
effect on only the current interface.
• If the same function or parameter is configured in both PIM view and interface view, the
configuration in interface view has preference over the configuration in PIM view, regardless of the
configuration sequence.
