Hi guys
Im trying to tunnel ipv6 from site A to site B over ipv4. When I assign ipv6 address to the tunnel interface (same subnet in the other side) everything work fine. But now I would like to use ipv6 unnumbered instead of the ipv6 address and I could not make it work, it look like im missing something..please look to the diagram and the configs.
