As someone suggested earlier, here you are trying to run auto-rp with
interfaces in sparse-mode.
You have to either,
change all the interfaces to "ip pim sparse-dense" OR
configure "ip pim autorp listener" in all routers for this to work.
BTW, can you ping interface IP addresses end-to-end (I mean normal ping)?
Sam.
