IE Task 7.6 - 7.7 Multicast RPF not working

  I am having a problem getting this task working. When a traceroute
From R2 to R5 using the loopback and ethernet addresses it takes the path
from R2 -> R1 -> SW1 -> SW2 -> R5. When I traceroute from R5 to R2 I take
the path R5 -> SW2 -> SW1 -> R1 -> R2 so I am not seeing an RPF issue. I
still cannot ping from R2 to R5 using the address 226.26.26.26 and I even
Added the static mroute's on R2 with no luck. Can someone please look at my
Config and tell me what I am missing ?

   Thanks in advance,

      Mike F.
