Overview
Use this command to define a non-default Source Specific Multicast (SSM) range of
IP multicast addresses in IGMP. Incoming IGMPv1 and IGMPv2 join requests are

configured for these addresses. By default, the SSM range is 232/8. To define the
SSM range to be other than the default, use one of the access-list parameter
options.
