Ping -6 not working in my windows

[praveen44com]

I am trying to do ping to the destination:
ping -6 2001:0:0:1::1 -S 2001::1
destination not reachable
destination port not reachable...

When i do ping from 2001:0:0:1::1 to 2001::1, ping is working fine...But in reverse way it is not working..
i done the routing like ths:
route add 2001:0:0:1::/64 2001::1

Whenever i try to do ping from 2001::1, system is trying to broadcase NS...
Can someone help me on this????
