root@LEDE:~# ps | grep -i odhcp6c
3106 root 1212 S grep -i odhcp6c
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

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.
It's possible to move selected postings to a) an existing topic b) a new topic.
@jow: click the wrench above the timeline, click Select, select the desired postings, then decide to move to new or existing topic.
Before we split the topics: I have just flashed the latest snapshot from the regular master branch, and IPv6 connectivity is back. Are we absolutely sure that the VLAN patches aren't to blame?
The issue already started when the build only contained the first commit (on our first try): https://git.openwrt.org/?p=openwrt/staging/jow.git;a=commit;h=72375f8e46d12d587721a25b24e4904b99fa0cc3
I noticed that you rebased (right?) your staging tree from the master tree. Is it worth compiling another build with the rebased staging tree with the VLAN patches included to check if this was patched in another master branch commit?
To be absolutely sure you can just build the master branch and apply the three vlan commits one by one and see if it breaks.
Comparing the swconfig dev switch0 show before and after each change would be helpful too.
After a some time compiling and testing I can confirm that the patches are fine It must have been something that was fixed in the master branch, which you pulled in when you updated your staging tree yesterday. A fresh compile from your staging tree is fully functional. VLANs are working properly, DHCPv6 and IPv6 connectivity is fine and the vids are all numbered correctly in the output:

It's been a long time since i initially started this thread, but i find it necessary to say
"THANK YOU"
to everyone who contributed to solving that problem. I am now using 4 of these devices in totally different VLAN configurations and all of them just work like a charm, regarding to the former VLAN problem.
