Ignore the complications added by SOb,
You are on the right track.
Vwlan are created on the wireless settings.
The difference mainly is that you have to choose the MASTER wireless interface be it WLAN1 or WLAN2.
The only difference in settings between the MASTER and the virtual is the SSID and security setting associated with SSID.
Then on the interface bridge ports treat them exactly like you do WLANs, pvid=???? the vlan you want that virtual WLAN to be using.
Same for interface bridge vlans as for the wlans.
/interface vlan
add name=wlan1 interface=bridge1 vlan-id=30
add name=wlan2 interface=bridge1 vlan-id=30
add name= virtualwlan1 interface=bridge1 vlan-id=50
add name=virtualwlan2 interface=bridge1 vlan-id=80
and name=unknownvlan interface=bridge1 vlan-id=39
/interface bridge
add name=bridge1 protocol-mode=none vlan-filtering=yes
/interface bridge port
add bridge=bridge1 interface=ether1 { assuming this is NOT the WAN port ?? )
add bridge=bridge1 frame-types=admit-only-untagged-and-priority-tagged interface=wlan1 pvid=30
add bridge=bridge1 frame-types=admit-only-untagged-and-priority-tagged interface=wlan2 pvid=30
add bridge=bridge1 frame-types=admit-only-untagged-and-priority-tagged interface=virtualwlan1 pvid=50
add bridge=bridge1 frame-types=admit-only-untagged-and-priority-tagged interface=virtualwlan2 pvid=80
/interface bridge vlan
add bridge=bridge1 tagged=bridge1,ether1 vlan-ids=39
add bridge=bridge1 tagged=bridge1,ether1 untagged=wlan1,wlan2 vlan-ids=30
add bridge=bridge1 tagged=bridge(maybe ether1) untagged=virtualwlan1 vlan-ids=50
add bridge=bridge1 tagged=bridge(maybe ether1) untagged=virtualwlan2 vlan-ids=80
This is basically the concept for the main wifi router.
If you have other Mikrotik devices that are wifi capable and they are connected to a main MT router via cable then they will not be needed as routers but will be acting as an AP/Switch.
If so then this article covers that........
