Ronnie,
Can you provide more info? It appears that you do not include any
interfaces on R1 in BGP and then on R2 you don't include 12.0.0.0 in RIP.
R2 can ping R1 because they both have interfaces int 12.0.0.0(no routing
required). I think R3s ping can't get back because R1 does not know how to
get back to R3.
