You can employ PIM-SSM even when receiverssupport 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 fromCONFIGURATION mode. In a standard access list, specify the groups or the group ranges that you wantto map to a source. Then, specify the multicast source.• When an SSM map is in place and Dell Networking OS cannot find any matching access lists for agroup, it continues to create (*,G) entries because there is an implicit deny for unspecified groups inthe ACL.PIM Source-Specific Mode (PIM-SSM) 613
