Multiple is something called bridged vlan, it means that all vlan share the same ip network and that there is full blocking between vlan in the same bridge,
bridged vlan can still communicate with other vlans like for example single vlan. very nice if you are going to create many vlans that are not going to talk to each other.

you create it this way

here is a guide you can look at

  @O2o 

If you want seperate vlans for different things, then just add new vlans and use either vlan isolation or gateway.switch ACLs to isolate them as needed.  Trunk the vlan tags down through trunk ports and set as native vlans on ports as needed.  Its very easy

Thanks you both for your replies that make sense.

Let me ask if TP-Link provides any blueprints for standard use-cases including comprehensive OMADA configuration?

  @O2o 

There is no definitive answer on how to set up a network, but you can find some information and FAQs that you can look at here.
