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 implementation of the SSM model is based on some subsets of PIM-SM. Therefore, you must
enable PIM-SM before configuring PIM-SSM.
When you deploy a PIM-SSM domain, enable PIM-SM on non-border interfaces of the routers.
