6.4.3 Enabling PIM-SM
The SSM model is implemented based on some subsets of PIM-SM. Therefore, a
router is PIM-SSM capable after you enable PIM-SM on it.
When deploying a PIM-SM domain, you are recommended to enable PIM-SM on all
interfaces of non-border routers (border routers are PIM-enabled routers located on the
boundary of BSR admin-scope regions).
Follow these steps to enable PIM-SM:

All the interfaces of the same router must work in the same PIM mode.
6.4.4 Configuring the SSM Group Range
As for whether the information from a multicast source is delivered to the receivers
based on the PIM-SSM model or the PIM-SM model, this depends on whether the
group address in the (S, G) channel subscribed by the receivers falls in the SSM group
range. All PIM-SM-enabled interfaces assume that multicast groups within this address
range are using the PIM-SSM model.
Follow these steps to configure an SSM multicast group range:
