Configuring the PIM-SSM Address Range

A range of multicast addresses is used for PIM-SSM. Within that address range, non-IGMPv3 messages are ignored, and any IGMPv3 exclude messages are ignored. These messages are ignored for all router interfaces, even those not configured for PIM-SSM. By default there is no PIM-SSM range specified on the router. If you choose the default keyword in the CLI when specifying the PIM-SSM range, you configure the range and default PIM-SSM range for IPv6 is FF3x::/96. You can also choose to specify a different range for PIM-SSM by using a policy file.

To configure the PIM-SSM address range, use the following command:

configure pim ssm range [default | policy policy-name]
