If you're using PIM Dense-Sparse mode you will need to designate an RP router because the DR needs to know where to send the (*,G) to join and the source DR needs to register the SA messages to the RP.
What you can do for this case is R1-----SP1-------SP2-----R2 make either R1 or R2 the RP. Assign a static RP-to-group mapping to the router that is not the RP to point to the one that is assigned the RP. If you're using static RP mapping then all you need on your tunnel interface is PIM-SM.
