Hello,
Is it be possible to create the wireless LAN using three hAP ax3 routers and a bunch of KVMs (Keyboard, Video and Mouse) as in the attached drawing and the following description?

1. Five or more VLANs or VxLANs crossing over Wi-Fi links
2. No connection to the internet/modem
3. No wireless clients
4. The KVM encoders and matching decoders are permanently connected to LAN ports and every piece of equipment has a static (pre-assigned) IP address

I've done this successfully using managed switches over Ethernet, but my attempts using Wi-Fi routers without the VLAN functionality failed. The only time I could get it to work was with just a single KVM pair which I hope will be improved with VXLANs.

The other issue was that I had to attach one router to a modem even though I had the DHCP server enabled on that router. I could detach the modem after the KVM decoder discovered the encoder and I still have no clue what could be done to solve that problem other than enabling the DHCP router and VXLANs.

Any advice/dissuasion/confirmation will be greatly appreciated.

Thanks in advance
