extend a guest wifi on second access point with OpenWrt using VLANs

In this episode we will extend a guest wifi in our home network as well as the IOT SSID and the LAN SSID which we have defined in the first episode to a second access point with OpenWrt using VLANs. Rather than setting up the second OpenWrt router as a fulll router, we will set it up as a so called "dumb access point" and extend the LAN, IOT and Guest networks over one single cable by defining a tagged VLAN port on both switches.
