Description
Configure source-specific multicast (SSM) groups.
By default, the SSM group multicast address is limited to the
IP address range from 232.0.0.0 through 232.255.255.255. However,
you can extend SSM operations into another Class D range by including
the ssm-groups statement in the configuration. The default
SSM address range from 232.0.0.0 through 232.255.255.255 cannot be
used in the ssm-groups statement. This statement is for
adding other multicast addresses to the default SSM group addresses.
This statement does not override the default SSM group address range.
IGMPv3 supports SSM groups. By utilizing inclusion lists, only sources that are specified send to the SSM group.
Options
ip-addresses—List of one or more additional SSM group addresses separated by a space.
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
