Configuring 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 is in the
SSM group range. All PIM-SM-enabled interfaces assume the PIM-SSM model for multicast groups within
this address range.
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.
