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.
Configuration restrictions and guidelines
When you configure the SSM group range, follow these restrictions and guidelines:
•
Configure the same SSM group range on all routers in the entire PIM-SSM 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.
