Multicast loop

I have some issue.
There is a network like in attached file.
  • PC1 sends multicast packet (with TTL > 1) to R1
  • R1 repeats packet into IF1_R and IF2_R
  • R2 repeats packets into IF1_R, IF2_R and IF_PC2
  • R1 repeats packets into IF1_R, IF2_R and IF_PC1
  • R2 repeats packets into IF1_R, IF2_R and IF_PC2
    ...and so on
How can I prevent of such a loop?
