udhcpc failure - route: SIOCADDRT: Invalid argument

[Tallam, Sreenivas]

Hi Denys,

Thanks for looking into this.
But unfortunately, even the net-tools one that one seem to be failing.

Please see the attached logs.

Thanks,
Sreen

Looks like you have static IPv6 configuration.
route command looks correct too, but it doesn't seem to succeed.
Looks like busybox's route applet is buggy.

Please do the following:

run "strace -o bb_route.log route -A inet6 add ::/0 gw
fd20:8b1e:b255:202::1"
and send me the log;

build (or take from other system) "standard" route (for example, one
from net-tools 1.60) and collect the same info from it:

strace -o std_route.log route_from_nettools -A inet6 add ::/0 gw
fd20:8b1e:b255:202::1
