I think you need iptunnel like this:

wget http://user:password@1.2.3.4/tunnelbroker/auto_anmeldung.php3
ifconfig sit0 down
ifconfig sit1 down
iptunnel del sit1
if ifconfig eth0 | grep -sq '3ffe:400:280:10::66' ; then
  ifconfig eth0 del 3ffe:400:280:10::66/126
fi
ifconfig eth0 add 3ffe:400:280:10::66/126
iptunnel add sit1 remote 1.2.3.4 mode sit ttl 64
ifconfig sit1 up
ifconfig sit0 up # this will add a "route add -A inet6 ::/96 dev sit0" route
route add -A inet6 2000::/3 dev sit1

note that in the above setup sit0 is not correctly set up, but I dont use
that IPv4 auto tunneling anyway. The 2000::/3 is another way of saying you
want to set up a defalt route ("default" does not work for all net-tools
versions).
