I'd appreciate to get some help about IPv6 configuration on Barrier
Breaker. I've configured two interfaces, lan and wlan, both with
option ip6assign '60'. But after reboot, it's only the lan interface
that has working IPv6.
odhcpd outputs: A default route is present but there is no public
prefix on br-wlan thus we don't announce a default route!
ifstate wan6 outputs:

Why don't odhcpd setup a working IPv6 also on wlan? Do you have any
hint? Please tell me if you need some more information to answer the question.
Thanks and regards,
