@Kevin_Z My ISP is Dvois I-ON Yes IPv6 is provided by ISP correctly and I am abe to get it when directly connected to laptop. But its not working on router. 1. What is your network topology, is it...

My router is not fetching the IPv6 address at all. If I connect my laptop directly to the ethernet, it is able to get IPv6 from ISP but it's not working with the router. I am using a PPPoE connection...
