Configuration Issues regarding IPV6

[KhaledJaber9762]

Hello to whom reading, 

I have configured ipv4 addresses successfully in this topology (shown in the attachment) Though I am struggling fairly with configuring IPV6 and getting them to ping from one device to another based on the topology given. I have tried using link-local ipv6 unicast routing, ipv6 routing but no succession. I have tried finding guides on assisting me with this but I have had no succession with succeeding the task handed based on utilising various sources. 

PC0 is the one having the most issues pinging as PC1 and PC2 cannot ping via IPV6 vice versa 

Thank you

Hi, unfortunately you've misconfigured the interfaces.

See attached image.

- The interfaces of the segment between the routers (highlighted in yellow) are not on the same subnet.

- Once you'll switch the addresses between Fa0/1 and Eth1/0, you'll have a duplicate IPv6 address.

Mend these issues and see if any more lack of functionality appears after that 🙂
