Section 4.5.1 says:

   The transition events "Receive Join(*,*,RP)" and "Receive
   Prune(*,*,RP)" imply receiving a Join or Prune targeted to this
   router's primary IP address on the received interface.  If the
   upstream neighbor address field is not correct, these state
   transitions in this state machine must not occur, although seeing
   such a packet may cause state transitions in other state machines.

   On unnumbered interfaces on point-to-point links, the router's
   address should be the same as the source address it chose for the
   Hello message it sent over that interface.  However, on point-to-
   point links we also recommend that for backwards compatibility
