I’d check that the script that udhcpc6 runs to configure IPv6 is actually doing
something sensible.
Especially if you are also trying to use IPv4 as well.
You’ll need a network that is running (IIRC) radv – otherwise you won’t get a
prefix length (aka netmask) or any routes.
So if IPv6 ‘autoconf’ (SLAAS) won’t give you a valid IPv6 config then neither
will dhcpc6.

Subject: Re: IPv6 support with busybox
Hi,
I installed busybox 1.29.3. I have tried to run tcpdump on my target to check
on issue.
I am running udhcpc6 by command - (udhcpc6 -b -p /var/run/udhcpc.usb0.pid -i
usb0)
Below is dump o/p. Please give me hints. Am I missing something?
-------------------------------------------------------------------------------------------------------
17:15:27.615913 IP6 (hlim 1, next-header UDP (17) payload length: 62)

Hi,
I would like to know from which version IPv6 support is available under
busybox. I learned there is separate dameon (udhcpc6) for IPv6.
I need to get an IPv6 address for Cellular network (M2M SIM).
Thanks
