Don't disable link-local address auto-generation.  You can assign your
own addresses, based on the /48 you have been given by your provider or
tunnel broker.  Something like this....

ifconfig fxp0 inet6 3ffe:dead:beef:cafe::/64 eui64 alias

That is only if you want to use auto-configured host addresses based on
the (IHMO) wasteful EUI64 junk... topic for another thread (and list,
probably!).  There are lots of differing opinions about the usefulness
of EUI64-based auto-config.
