My intention is to extend WiFi coverage by adding another AP into the chain.
Internet <---> VDSL <--Eth--> TO (w DHCP) <--Eth--> DumbAP
.............................. / .. \ ............. / .. \

....................... SSID1 SSID2 SSID1 .. SSID1 SSID2 SSID1
Of course SSID 1 is regular and SSID2 is meant to be GuestWlan with different IP range and Firewall policies.
DumbAP is not as Dumb it will be VLAN etc capable as it will become another TO, or OpenWRT in my case, configured in accordance to https://openwrt.org/docs/guide-user/network/wifi/dumbap.
My assumption is there will be necessary to do additional VLAN and establish trunk connection between TO and DumbAP.
Is there any recommended way to create VLANs under 5.x branch? It was rather “easy=I understand” under 3.x branch; however I am confused under 5.x what should be configured and the configuration should survive regular Omnia updates.
Here, on the forum I have just found https://forum.test.turris.cz/t/2x-omnias-one-as-router-second-as-ap/5763 which has no answer at all and is 3 years old and TOS5 VLANs: https://forum.test.turris.cz/t/tos5-vlan-nightmare/13175.
The most promising is following thread: https://forum.test.turris.cz/t/total-obsolete-vlan-documentation/13121/25 ; however some common approach would be better as different setup will lead into future nightmare.
