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.
