Note!
If interfaces have not been configured with IPv6 addresses yet, use fc00:1:1::/64 as the network-ID and ::x, as a host ID (where x=router-ID).

Task 1
You no longer have to support other protocol while connecting the IPv6 networks in our topology (pic. 1). Reconfigure previous labs in such a way that the tunnel allows only IPv6 over IPv4 between R1 and SW4.Solution
