Ashok,
By design, PIM sparse and dense modes will not send traffic out the incoming
interface. This is part of the PIM method for creating loop free trees.
More formally, the incoming interface will not show up on the outgoing
interface list of the S,G entry.
In order to get the multicast stream through R1 to R2, you will need to have
it arrive one one R1 interface (or subinterface) and leave on another.
HTH,
