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.

•
Configure PIM-DM or PIM-SM.
Configuring a multicast source policy
This feature enables the device to filter multicast data by using an ACL that specifies the multicast
sources and the optional groups. It filters not only data packets but also register messages with
multicast data encapsulated. It controls the information available to downstream receivers.
To configure a multicast source policy:
