PIM Source-Specific Mode | 779Implementation Information• The Dell Force10 implementation of PIM-SSM is based on RFC 3569.• C-Series supports a maximum of 31 PIM interfaces and 4K multicast entries including (*,G), and(S,G) entries. There is no limit on the number of PIM neighbors C-Series can have.• S-Series supports a maximum of 31 PIM interfaces and 2K multicast entries including (*,G), and (S,G)entries. There is no limit on the number of PIM neighbors S-Series can have.• E-Series supports a maximum of 511 PIM interfaces and 50K multicast entries including (*,G), (S,G),and (S,G,rpt) entries. There is no limit on the number of PIM neighbors E-Series can have.• FTOS reduces the number of control messages sent between multicast routers by bundling Join andPrune requests in the same message.Important Points to Remember• The default SSM range is 232/8 always. Applying an SSM range does not overwrite the default range.Both the default range and SSM range are effective even when the default range is not added to theSSM ACL.• Extended ACLs cannot be used for configuring SSM range. Be sure to create the ACL first and thenapply it to the SSM range.• The default range is always supported, so range can never be smaller than the default.Configure PIM-SMConfiguring PIM-SSM is a one-step process:1. Enable PIM-SM. See page 758.2. Enable PIM-SSM for a range of addresses. See page 780.Related Configuration Tasks• Use PIM-SSM with IGMP version 2 Hosts on page 780
