Hi,
When i ping from pc it says request time out. PC is connected to switch and switch is connected to router.
I can ping to other PCs which are connect to the switch and its getting reply. only issue is when i ping router it says request time out. All ip address are IPV6 and default gateway is also set in all 3 PCs which are connected to the router.
Thanks

Pls try with below enabled:
# ipv6 unicast-routing
# ipv6 cef
Please refer the below document as well.

Thanks Dear,
Issue is fixed now.
Now i am able to ping router from LAN PC.
I will go ahead and configure static routing to ping PC from one network to another network.

Hi,
Are you trying to have connectivity based on link-local addresses or based on global-unicast addresses? Go on a PC, issue "ipconfig /all" and see your link-local and global unicast addresses. Go on the router and perform "show ipv6 interface x/y/z". See if both the router and user are in the same subnet, if not fix it. Regardless of being in the same subnet or not, if layer 2 is functional end-to-end, you should be able to have connectivity on the link-local addresses. If not, try to ping on the link-local address, and on the router perform "show ipv6 neighbors" to see if IPv6-MAC resolution has been successful.

Cristian Matei.

The Neighbor solicitation times out when the router tries to send the icmp packets as per the simulation.
Also try to use the "ipv6config " on the command prompt to see the ipv6 address on the end host.
I simulated in Packet tracer, will try on other software and revert if the same config works there.
For more information on Router solicitation refer to the document.
I hope this helps with your issue.

Manoj
