@jow I did a little more testing. And flashing back 17.01.4 while keeping the settings instantly brings back IPv6 connectivity. Obviously, VLAN 8 is broken again. Is there anything else I can do testing-wise to help pinpoint the issue? Maybe try out the master branch without your patches to see whether it is something caused by a commit in the master branch that's not there in 17.01.4 yet?
Hmm, whats reported in logread after ifdown wan; ifup wan on master?
Master as in the build that I compiled yesterday including your patches? Or master as in the the current master branch without the VLAN patches?
I mean my staging tree.

edit 1: Actually, I think I am just grepping the grep process itself here. Let me double check.
edit 2: http://192.168.1.1/cgi-bin/luci/admin/status/processes doesn't show 'odhcp6c'
edit 3: Do I need to manually include that package when compiling my own firmware? Or is it enabled by default? That might have been the issue otherwise 
Hm, usually odhcp6c is part of the default package set, but does not hurt to double-check that it is installed. Is the package listed by opkg list-installed odhcp6c ?

edit: The wan_6 interface seems to be missing. But I am not sure whether it was there on Lede 17.01.4. I could double check that if that is useful information
Hm, and you want interface's option ipv6 is set to auto? Does uci get network.wan.ipv6 report auto?
I've tried both auto and 1. It's currently set to 1.
Please set it to auto and repeat the tests above (ps grep, ifstatus etc.)

}Ok, is odhcp6c running now, after the change to auto?
Yes
root@LEDE:~# ps | grep -i odhcp6c
4535 root 1032 S odhcp6c -s /lib/netifd/dhcpv6.script -P0 -t120 pppoe-wan
5579 root 1212 S grep -i odhcp6cOkay, so the machinery appears to work but odhcp6c is unnable to obtain a DHCPv6 lease.
This might be a bug or quirk with the client which seems untelated to the switch topic. We should open a new topic for that to not further deviate here.
Agreed. Would it be possible to migrate the current posts about the IPv6 issues to another topic instead of starting over? That way, the entire discussion will be easier to follow for other people running into the same/similar issues.
Unfortunately not, but you can place a link to this topic, it will appear in both threads then.
