No C-BSRs are configured for
the global-scoped zone by

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.
Configuration guidelines
• When the system is operating in standard mode, you must configure a reserved VLAN before you
configure PIM-SM for a VPN instance. For more information about the system operating mode, see
Fundamentals Configuration Guide. For more information about a reserved VLAN, see MPLS
Configuration Guide and MPLS Command Reference.
• All the interfaces of a switch that are in the same VPN instance must share the same PIM mode.
• When deploying a PIM-SSM domain, enable PIM-SM on non-border interfaces of the routers.
