PIM-SSM configuration task list
Task Remarks
Enabling PIM-SM Required
Configuring the SSM group range Optional
Configuring PIM common features Optional
Configuration prerequisites
Before you configure PIM-SSM, complete the following tasks:
Configure any unicast routing protocol so that all devices in the domain are interoperable at the
network layer
Determine the SSM group range
Enabling PIM-SM
The SSM model is implemented based on some subsets of PIM-SM. Therefore, you must enable PIM-SM
before configuring PIM-SSM.
When deploying a PIM-SSM domain, enable PIM-SM on non-border interfaces of the routers.
To enable PIM-SM globally on the public network:

4. Enable PIM-SM. pim sm Disabled by default.
For more information about the multicast routing-enable command, see Network Management
Command Reference.
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.
Perform the following configuration on all routers in the PIM-SSM domain.
To configure an SSM multicast group range:
