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.
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.
Perform the following configuration on all routers in the PIM-SSM domain.
To configure an SSM multicast group range:
Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Configure the SSM group
range.
