[OpenWrt-Devel] 6rd issues with 18.06-rc2 on ubnt-erx-sfp

[Torbjorn Jansson]

Hello

i decided to try to upgrade my erx-sfp from an old snapshot (probably a year or 
so old) to 18.06-rc2.
for the most part it worked out but there is something odd going on with my 6rd 
wan interface and i'm not sure where to start the troubleshooting.

with luci-proto-ipv6 and 6rd packages installed i get a lot of stuff like this 
in syslog:
14:29:07 2018 daemon.notice netifd: wan6 (24771): Command failed: Unknown error
14:29:07 2018 daemon.notice netifd: Interface 'wan6' is now down
14:29:07 2018 daemon.notice netifd: Interface 'wan6' is setting up now
14:29:08 2018 daemon.notice netifd: wan6 (24856): Command failed: Unknown error
14:29:08 2018 daemon.notice netifd: Interface 'wan6' is now down
14:29:08 2018 daemon.notice netifd: Interface 'wan6' is setting up
(dates removed to make log easier to fit in mail without line breaks)

this repeats every second and 6rd interface seems to get ip adress but it is 
not quite working.

plus i noticed under Network -> Interfaces in webinterface i now have two 
similar looking 6rd interfaces.
one named WAN6 and thats the one i created and another one that cant be edited 
that's called WAN_6

WAN6 is listed as protocol: IPv6-over-IPv4 (6rd)
WAN_6 is listed as protocol: Virtual dynamic interface (IPv6-over-IPv4 (6rd))

the last interface must be something new or a problem or something.
it is also that interface that gets the ipv6 addresses.


any idea whats wrong?
or how to find out what command failed in the log?
