Scenario:
PIM dense mode.
R2 deny 224.1.1.1 but allow 224.2.2.2
R3 can ping 224.1.1.1, 224.2.2.2

Question: How can I config R2 to filter out 224.1.1.1 w/o breaking connectivity between R1 and R3?
note that R3 is required to be able to ping both groups.

                     s0 R1 IGMP group 224.1.1.1, 224.2.2.2
                   /
                 /
  s0.1 point2point
R2
  s0.2 multipoint
                 \
                   \
                     s0 R3
