hello multicast experts !!

here is my topology...R2 is a hub for R1 & R3 and R3 is a hub for R5 & R4
and only the links in Red (color) are running sparse-dense mode. R5 is
joined group 226.26.26.26. I am some how not able to ping the group from
R2.I have connectivity to all the interfaces.. R5 is reachable from R2 via
R1, but the mcast static route is configured thru R3. And R3's loop 0 is the
RP..Any insight ?
