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 into 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-SSM domain.
Follow these steps to configure an SSM multicast group range:

To do...

Use the command...

Remarks

Enter system view

Enter public network PIM view or

Configure the SSM group range

ssm-policy acl-number

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.
