Difference between tunnel modes: GRE/IP versus IPv6/IP

Hi All,

Could someone explain to me the difference between GRE/IP and IPv6/IP
tunnel modes when the GRE/IP tunnel has an IPv6 address configured at
each end.

Both tunnel modes have an IPv4 source and destination address. The only
difference I can spot is in the "show int tunnel x" command where the
Tunnel protocol/transport is shown differently. I can't spot any
difference in functionality at the moment.

regards Andy
