say you have
2001:db8:23::1/64 and fdac:23::1/64 configured on ix0 and the following
rad.conf:
interface ix0 {
prefix fdac:23::/64 { autonomous address-configuration no }
auto prefix { autonomous address-configuration yes }
}
rad should announce 2001:db8:23::/64 with the A flag set and
fdac:23::/64 without the A flag.
Currently it announces both prefixes with the A flag because auto
prefix wins. I believe that is the wrong way around.
Ross Richardson pointed a use case out in private where you get a
dynamic global prefix via dhcpv6-pd and you want a stable ULA prefix
for your infrastructure but don't want to use the ULA for slaac.
currently that's not possible.
OK?

I'm not entirely sure you are real.
