No need for shared trees or RP mapping (no RP is required).
No need for RP-to-RP source discovery through Multicast Source Discovery Protocol
(MSDP).
Simplified administrative deployment; you need only configure PIM sparse mode on
all router interfaces and issue the necessary SSM commands (including specifying
MLDv2 on the receiver local area network).
Support for source lists; you can use source lists, supported in MLDv2, where only
specified sources send traffic to the SSM group.
In a PIM SSM–configured network, the E Series router subscribes to an SSM channel (by
means of MLDv2), announcing a desire to join group G and source S. The directly
connected PIM sparse mode router, the designated router of the receiver, sends an (S,G)
join message to its RPF neighbor for the source. For PIM SSM, the RP is not contacted in
this process by the receiver (as happens in normal PIM sparse mode operations).
