This is OpenWrt 18.06.1on TP-Link Archer C7 v2
I have two subnets, one private and one guest network.
The private network is on interface HOME which is a bridge of eth0, wlan0, wlan1. The guest network is on interface LET which is a bridge of eth1, wlan0-1, wlan1-1. Each of the two WiFi radios thus spans two WiFi networks, one to access the private and one to access the guest network.
This works flawlessly for IPv4 where the OpenWrt box has a static IPv4 address and the clients get their IPv4 addresses from the upstream firewall appliance connected to eth0 and eth1.
The OpenWrt box does only get link-local IPv6 addresses although the upstream firewall appliance has a Router Advertisment Daemon running and all workstations in the private network get their IPv6 addresses from the firewall appliances.
This is what ifstatus home (the interface on the private network) gives:

I read the docs and searched the forum but I am unsure where to start making changes. Please let me know what config files I should show you to be able to help me.

Excellent. A million thanks for your precise help. This works as desired. The OpenWRT box as well as mobile devices connected to its wireless networks get IPv6 addresses from the
