Hi admin@atrinnet.net ,

Yes, it is possible. It would look something like this.

feature tunnel

interface Tunnel1
ip address 192.168.12.2/24
tunnel mode gre ipv6
tunnel source 2001:db8:12ff:12::2
tunnel destination 2001:db8:12ff:12::1
no shutdown

Also, bear in mind that the ipv4 MTU will be reduced by 44 bytes (40 bytes for ipv6 header + 4 bytes for GRE header).
