Configuring the SSM Group Range
As for whether the information from a multicast source is delivered to the receivers based on the PIM-SSM
model or the PIM-SM model, this depends on whether the group address in the (S, G) channel subscribed
by the receivers falls in the SSM group range. All PIM-SM-enabled interfaces assume that multicast
groups within this address range are using the PIM-SSM model.
Perform the following configuration on all routers in the PIM-SM domain.
Follow these steps to configure an SSM multicast group range:
To do... Use the command... Remarks
Enter system view system-view —
Enter public network PIM view pim —

Optional
232.0.0.0/8 by default
CAUTION:
•
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
report message, the device does not trigger a (*, G) join.
