OpenWRT 21.02 - Guest Network & Extended with Dumb AP/Router

In this video, we are going to setup Guest LAN network on OpenWRT router. And then, we are going to extend this guest Network with a Dumb AP/Router. As a result, you will have a second network for your guest or IoT devices that works independently and won't be able to connect to the main LAN/OpenWRT management interface.
For this setup, I used the Linksys WRT1900AC as the main router with LAN port 1 was configured as Guest LAN port. The Dumb AP is actually the Xiaomi CR6608 router, with DHCP disable and it was connected to the WRT1900AC by the LAN port.
