I have configured R1, R2 and R3 with IP v6 static routes and i am able to test a successful ping between Pc1 and Pc2 however the ping fails when run from either R1 or R3 however succeeds when run from R2. Also i have enabled IPv6 unicast routing on R1, R2 and R3. Where could be the problem @Flavio Miranda ?
Attached is topology and running config for R1, R2 and R3.
Thanks in Advance.

Hi @packet4737 ,
I just realized that Packet Trace does not allow to specify the source address on the ping command.
You could add the following routes to allow R1 to ping R3 and vice versa:
R1:
ipv6 route 2001:DB8:0:23::/64 2001:DB8:0:12::2
R3:
ipv6 route 2001:DB8:0:12::/64 2001:DB8:0:23::1

I´d like to see the project. But, what you are saying dont make sense to me. If you can ping from PC you should be able to ping from router.
Have you tried use ping and put the source interface?

Hello @packet4737
As the PacketTracer seems to not allow source ping with IPV6, I fixed the problem by adding default route on both routers like this:
R1:
ipv6 route ::/0 2001:DB8:0:12::2
R3:
ipv6 route ::/0 2001:DB8:0:23::1
R1#ping 2001:DB8:0:3::100
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:DB8:0:3::100, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/0 ms

Hi @packet4737 ,
R1 only has a static route to 2001:DB8:0:3::/64 and R3 only has a static route to 2001:DB8:0:1::/64. you need to specify the source interface when you ping from R1 and R3.
R1:
ping 2001:DB8:0:3::1 source gigabitEthernet 0/1
R3:
ping 2001:DB8:0:1::1 source gigabitEthernet 0/1

Hi @packet4737 ,
> help me clarify this behaviour and the failure to achieve 100% successful Ping from R1
Not sure what the issue might be. I loaded the Packet Tracer file you provided and applied the static routes I suggested and I get the following results.
R1#ping 2001:DB8:0:3::1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:DB8:0:3::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/1 ms
R1#ping 2001:DB8:0:3::100
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:DB8:0:3::100, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/3/15 ms
R3#ping 2001:DB8:0:1::1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:DB8:0:1::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/0 ms
R3#ping 2001:DB8:0:1::100
Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 2001:DB8:0:1::100, timeout is 2 seconds:

Success rate is 100 percent (5/5), round-trip min/avg/max = 0/3/16 ms
