All PIM-SM-enabled interfaces assume that multicastgroups within this address range are using the PIM-SSM model.Configuration guidelines• Make sure that 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 reportmessage, the device does not trigger a (*, G) join.Configuration procedurePerform the following configuration on all routers in the PIM-SSM domain.To configure an SSM multicast group range:Step Command Remarks1.

In interface view, the configuration iseffective on only the current interface.• If the same function or parameter is configured in both PIM view and interface view, theconfiguration in interface view has preference over the configuration in PIM view, regardless of theconfiguration sequence.PIM common feature configuration task listTask RemarksConfiguring a multicast data filter Optional
