Tunnel mode ipv6ip

Hey team,

If you run ipv6 addressing and routing over a tunnel, do you still need the
tunnel mode "ipv6ip"?

I had to connect two 'islands' of ipv6 with a tunnel.

I was allowed to add another ipv4 and ipv6 network. Pretty easy huh ... and
all seemed to work. The solution guide included the tunnel mode ipv6ip.
Would adding this command get me anything extra?

Many TIA,
