H3C S5500-EI - Configuration Prerequisites; Enabling PIM-SM

175
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 deploying a PIM-SSM domain, enable PIM-SM on non-border interfaces of the routers.
IMPORTANT:
A
ll the interfaces in the same VPN instance on the same device must operate in the same PIM mode.
