Configuration prerequisites
Before you configure PIM-SSM, configure a unicast routing protocol so that all devices in the domain
can interoperate at the network layer.
Enabling PIM-SM
Before you configure PIM-SSM, you must enable PIM-SM, because the implementation of the SSM
model is based on subsets of PIM-SM.
When you deploy a PIM-SSM domain, enable PIM-SM on non-border interfaces of the routers.
IMPORTANT:
All the interfaces on a device must be enabled with the same PIM mode.
To enable PIM-SM:
