WDS link for private and guest network VLANs

Installing and Using OpenWrt Network and Wireless Configuration
1

I want to extend the coverage of the private and guest Wi-Fi network. How should I configure to be able to use via a WDS link?

2

Set up a secondary router / dumb AP (same network, no routing, no dhcp) on same networks, add "option wds 1" both sides, both networks.

A wireless client can only connect to a single access point, you cannot have the same repeater client connect to two networks on the main router.

Easiest solution is probably to use the 5GHz band for one network, and the 2.4GHz band for the other. You can bridge the APs on the repeater, so your clients can connect to any band.

The other.soolution is to tunnel one network inie the other, for example using GRE.

Whoopsie, you're right: when I was using WDS (3yrs ago) I only had one SSID and 1 radio! I had extrapolated without checking, my bad.

Yes, I know that only one client can connect to an AP. What I'm asking is how to make the traffic from the private and guest network go through the same WDS link since in the second router there is only one radio and I can't use 5GHz as return. I think the solution is on the VLANs side or as you say, tunnels.
I used Batman but I see that it is convenient when there are several mesh points and not a point to point as in my case.

Ready! And how to make the guest traffic go through the WDS link?

Here is the configuration of each point:

See this thread, where I explained the process I followed in a similar situation:
