It depends on what the requirements are (or what the guy writing the lab was
thinking of). In earlier versions of IOS, GRE and IPv6 wasn't fully baked
yet.
But now that things work fine, you have two choices. What's the difference?
Size.
IPv6IP will have less headers than GREIPv6. Otherwise, both of them tunnel
and both of them move IPv6 packets through an IPv6 network.

Subject: IPv6 Tunnel
Hi All,
When creating IPv6 tunnels, there are a couple of tunnels modes available.
The default without using any "tunnel mode XXX' commands will be GRE/IP
mode.
I noticed IE is always using "tunnel mode ipv6ip" even though task didnt
explicity specify using what modes.
Is there any chances of good practices to use 'ipv6ip' over 'GRE'.
Cheers
Nit
