Four routers are connected as circle like this: A ---- B ----C ----D, and A is connected to D. So each router has the same distance cost to other. When multicast packet goes from A to C, it will have the same cost to C through B or D. My question is which interface is RPF of C? In other word, C should receive packet from B or D, or both? Thanks

Thank you for your fast reply. the below picture is from your link. Here is my question: when the cost is lower through R2 than R3, the routes go from R2, and gi0/1 is RPF. but when the cost is same at R2 and R4, the routes will have balance. that means the two interface gi0/1 and gi0/2 at R4 get the routes. If this is case, which interface is RPF?
