Are there any other routers involved in ospf? You might be getting some route feedback which violates your rpf check

I have a scenario where
1. R1 is hub and R2,R3 spokes.
2. OSPF is running on main interfaces as NBMA mode.
3. AutoRP is running on Hub R1.
4. igmp join for 224.1.1.1 is on R3's ethernet.

Problem: Not able to ping 224.1.1 from R1. If I give reapeat count 10, first
ping succeeds but then it stops,
              From R1 to R3 ping is ok.

I tried with ip pim nbma mode on Hub and ip pim spt-threshold infinity on R3
, It does not help.
