Configuring PIM-SSM

PIM-SSM requires IGMPv3 support. Enable IGMPv3 on PIM routers that connect to multicast receivers.

Configuration prerequisites

Before you configure PIM-SSM, configure a unicast routing protocol so that all devices in the domain are
interoperable at the network layer.

Enabling PIM-SM

The implementation of the SSM model is based on subsets of PIM-SM. Therefore, you must enable
PIM-SM before configuring PIM-SSM.
When you deploy a PIM-SSM domain, enable PIM-SM on non-border interfaces of the routers.
IMPORTANT:
All the interfaces on a device must be enabled with the same PIM mode.
To enable PIM-SM:
Step
1. Enter system view.
2. Enable IP multicast routing,
and enter MRIB view.
3. Return to system view.
4. Enter interface view.
5. Enable PIM-SM.

Configuring the SSM group range

When a PIM-SM enabled interface receives a multicast packet, it checks whether the multicast group
address of the packet is in the SSM group range. If the multicast group address is in this range, the PIM
mode for this packet is PIM-SSM. If the multicast group address is not in this range, the PIM mode is
PIM-SM.
