Yes, that is gif.
>From 'man 4 gif':
The gif interface is a generic tunnelling pseudo device for IPv4 and
IPv6. It can tunnel IPv[46] traffic over IPv[46]. Therefore, there can
be four possible configurations. The behavior of gif is mainly based on
RFC2893 IPv6-over-IPv4 configured tunnel. On NetBSD, gif can also tunnel
ISO traffic over IPv[46] using EON encapsulation.

Try this:
ifconfig gif2 create
ifconfig gif2 tunnel 193.68.159.71 193.25.126.2
ifconfig gif2 inet6 3ffe:200:107:ffff::4:2 prefixlen 112 up
route add -inet6 default 3ffe:200:107:ffff::4:1
You don't need the 2 other route commands. ifconfig should call SIOCSIFADDR
which sets up relevant connected link-local routes in the inet6 kernel
routing table.

Actually, just emailing here was the correct approach in requesting an AS :-)
Here is your AS Number: AS64581
Please go to http://www.occaid.org/irrd-tutorial.html and register your
maintainer object and AS object. You do not need to register route objects
as currently our database only supports ipv4 at the time being. When we upgrade
with newer version of Merit IRRD software later that supports ipv6, we will
let people know. So for now just register AS Object after your maintainer
obj is accepted.
P.S.: To Peter:
I have modified your filtering list as below..
# sh ipv prefix pl31292
ipv6 prefix-list pl31292: 3 entries
seq 5 permit 3ffe:200:107::/48 le 64
seq 10 permit 3ffe:80ee:23d8::/48
seq 50 deny ::/0 le 128
#
no ip as-path access-list 31292 permit ^(31292_)+
ip as-path access-list 31292 permit ^_(31292_)+(64581_)*$
You may choose to filter out his private ASN before announcing to OCCAID, that
is completely up to your routing policy at 31292. Regardless, OCCAID will
automatically tag any private-ASN sourced prefix, or RFC2772 violated prefix
with 30071:31337 community tag, which means do not export to anyone outside
of our AS.
