What about the IPV6 routing table of R2?
You are trying to ping R3s loopback address from R1, but R2
doesnt have a route to the loopback 0 address...
I am not sure weather you a are allowed to use other IP addresses than
the ones you used. 2002::/16 prefixes are reserved for 6to4 tunnels, and
I am not sure if router 1 misses a tunnel, if configured with such an
address...
Just some ideas...
