781BPIM-SSM configuration task list
Complete these tasks to configure PIM-SSM:
Task Remarks
2811H
Enabling PIM-SM Required.
2812H
Configuring the SSM group range Optional.
2813H
Configuring common PIM features at the CLI Optional.
782BConfiguration 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.
783BEnabling 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.
To enable PIM-SM:

784BConfiguring the SSM group range
Whether the PIM-SSM model or the PIM-SM model delivers the information from a multicast source the
receivers depends on whether the group address in the (S, G) packets that the receivers request falls into
the SSM group range. All PIM-SM-enabled interfaces assume the PIM-SSM model for multicast groups
within this address range.
1. Configuration guidelines
• Perform the following configuration on all routers in the PIM-SSM domain.
• Make sure the same SSM group range is configured on all routers in the entire domain. Otherwise,
multicast information cannot be delivered through the SSM model.
• When a member of a multicast group in the SSM group range sends an IGMPv1 or IGMPv2 report
message, the device does not trigger a (*, G) join.
