6to4 routers


Hi,

I made some more investigation on the 6to4 mechanism. In fact, there
is no need to explicitly give a router for your 6to4 traffic any
more. There is a special magic (anycast) address 2002:c058:6301::
(which corresponds to the 6to4 prefix corresponding to IPv4 address
192.88.99.1) defined in RFC 3068, which means "the nearest 6to4
router".

So, Rudi, you can do:

ip -6 route del default via ::139.18.38.73
ip -6 route add default via 2002:c058:6301::

and then, you'll start using the nearest router to you, instead of the
university of Leipzig one. (Note that for me, the uni-leipzig one
isn't the closest (a machine belonging to eurocyber.net, in Germany,
is), but has better ping times than the closest. YMMV.)

Please let me know if it works, I'm very curious. If it doesn't work,
try

ip -6 route del default via 2002:c058:6301::
ip -6 route add default via ::192.88.99.1


And by the way, the "List of public 6to4 routers" that was unavailable
during the meeting is back online: http://www.kfu.com/~nsayer/6to4/
