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

SSM range to be other than the default, use one of the access-list parameter
options.
Use the no variant of this command to change the SSM range in IGMP back to the
default.
