ip access-list standard name
2. Enter the ip pim ssm-range command and specify the ACL you created.
CONFIGURATION mode

Use PIM-SSM with IGMP Version 2 Hosts
PIM-SSM requires receivers that support IGMP version 3. You can employ PIM-SSM even when receivers
support only IGMP version 1 or version 2 by translating (*,G) entries to (S,G) entries.
Translate (*,G) entries to (S,G) entries using the ip igmp ssm-map acl command source from
CONFIGURATION mode. In a standard access list, specify the groups or the group ranges that you want
to map to a source. Then, specify the multicast source.
