PIM sparse mode.
• Skip this step if you are configuring sparse-dense mode in Step 8.
Selects an interface that is connected to hosts on which PIM can be
enabled.
Enables PIM sparse mode on an interface. When configuring Auto-RP
in sparse mode, you must also configure the Auto-RP listener in the next
step.
• Skip this step if you are configuring sparse-dense mode in Step 8.
Enables PIM sparse-dense mode on an interface.
• Skip this step if you configured sparse mode in Step 7.
