Autoconfiguration works fine, even with multiple IP addresses. The
setup we used to test was a Cisco as the router (which also announced
the address range), a Linux 2.2 and FreeBSD 4.0 with KAME.

I couldn't find the code that chooses which one of multiple addresses
to use. Prefixes announced by a router have a time to live, and the
kernel should choose the longer-living address over an equally suited,
but shorter TTL address for outgoing connections. This allows you to
change address space without breaking anything, without even having to
reboot anything. But I'm not sure Linux handles this properly yet.
