Configuring Additional Source-Specific Multicast Groups

IGMPv3 supports Source Specific Multicast (SSM) groups. By utilizing inclusion lists, only sources that are specified send to the SSM group. By default, the SSM group multicast address is limited to the IP address range 232.0.0.0 to 232.255.255.255. You can configure additional SSM groups. Shared tree delivery is prohibited on SSM groups.

To configure additional SSM groups, include the ssm-groups statement:

ssm-groups {address;}

For a list of hierarchy levels at which you can include this statement, see the statement summary section for this statement.
