Configuring The Ssm Group Range - HP 4800G Series Configuration Manual

Enabling PIM-SM
The SSM model is implemented based on some subsets of PIM-SM. Therefore, a router is PIM-SSM
capable after you enable PIM-SM on it.
When deploying a PIM-SM domain, you are recommended to enable PIM-SM on non-border interfaces
of the routers.
Follow these steps to enable PIM-SM globally
To do...
Enter system view
Enable IP multicast routing
Enter interface view
Enable PIM-SM
All the interfaces on the same device must work in the same PIM mode.
For details about the multicast routing-enable command, see Multicast Routing and Forwarding
Commands in the IP Multicast Volume.

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:
