registratin failing due to rpf .

HI experts

 R5 is the designated router . but registration is not happening ...debug
says RPF issue . however i am able to trace form the source up to the RP

and form DR back to source .... problem is the router not saying for what
RPF IS failing ..IS IT FOR RP OR FOR SOURCE ...BUT MTRACE IS SUCCESSFULL

Any idea when it says """" *RPF lookup failed for source or RP """"
*
