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.  

Perform the following configuration on all routers in the PIM-SM domain. 

Follow these steps to configure an SSM multicast group range:  

To do... 

Use the command...

z 

Make sure that the same SSM group range is configured on all routers in the entire domain. 

Otherwise, multicast information cannot be delivered through the SSM model.  

z 

When a member of a multicast group in the SSM group range sends an IGMPv1 or IGMPv2 report 

message, the device does not trigger a (*, G) join.
