  To configure ip6-in-ip6 tunnle, you can use ipv6tunnel.

  It is installed as /usr/local/v6/sbin/ipv6tunnel.

ex.
--------------------------------------------------
# modprobe ip6_tunnel (if you built with CONFIG_IPV6_TUNNEL=m)
# ipv6tunnel add mytun0 remote ::1 local ::1 dev eth0 encaplimit none
# ifconfig mytun0 up
# ifconfig mytun0
mytun0    Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00  
          inet6 addr: fe80::20b:dbff:fe5a:8063/64 Scope:Link
          UP RUNNING NOARP  MTU:1460  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:3 dropped:3 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

# 
--------------------------------------------------
  Unfortunately, ip4-over-ip6 cannot be configured.
