16.1.8 IPv4 PIM-SSM Setting

The example below shows how to specify the settings shown below in global configuration mode, to use IPv4 PIM-SSM for the Switch. These settings cause IPv4 PIM-SSM to run within the specified SSM address range on interfaces for which IPv4 PIM-SM is set. Only one SSM address setting can be used on the Switch. In this example, the default (232.0.0.0/8) is used for the SSM address range for which PIM-SSM runs. To specify the SSM address range, use the ip pim ssm range command.

Because source addresses cannot be differentiated with IGMPv2 or IGMPv3 (EXCLUDE mode), linkage to the PIM-SSM cannot be performed. With the Switch, the group address and source address for which PIM-SSM is run can be set to link with PIM-SSM. The group address for which PIM-SSM is run needs to be within the SSM address range specified by the IPv4 PIM-SSM address setting. For example, the following figure shows a PIM-SSM configuration in which the group address is 232.10.10.1 and the source address of Server 1 is 192.168.1.2 and the source address of Server 2 is 192.168.2.2.
