Configuring PIM Sparse-Dense Mode Properties

To configure PIM to operate in sparse-dense mode on an interface, include the mode sparse-dense statement. Include the dense-groups statement to specify which groups are operating in dense mode:

You can configure both IPv4 and IPv6 addresses in the dense-groups statement. For a list of the hierarchy levels at which you can include these statements, see the statement summary section for this statement.

You can configure graceful restart with PIM sparse-dense mode, but only sparse multicast groups benefit from graceful restart. For more information about graceful restart for PIM sparse mode, see Configuring PIM Sparse Mode Graceful Restart.

For an example of a sparse-dense mode configuration, see Example: Configuring PIM Sparse-Dense Mode.
