Hmm, could you describe the error you are getting?
I cannot reproduce it in my environment.

...or is it about setting IPv6 address for the second time on the interface,
because network.sh and test_net.sh are both using the same '-6' option?

network_settings 1 TINFO : set local addr fd00:1:1:1::2/64
RTNETLINK answers: File exists

Moreover, it's not needed to set TST_USE_NETNS.

Thanks,
Alexey
