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...
Enter system view
Enter public instance PIM view
or VPN instance PIM view
Configure the SSM group
range
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.

Configuring PIM Common Features

Use the command...
system-view
pim [ vpn-instance
