Yes, MikroTik supports up to 4095 vlans as well as allowing Q-in-Q.

VLANs (Virtual Local Area Networks) can be configured on MikroTik RouterBoard devices. VLANs are an essential tool in network management, as they allow a physical network to be segmented into multiple independent virtual networks, which improves the organization, security and management of traffic within a network.

To configure VLANs on a RouterBoard, you can follow these general steps, keeping in mind that the details may vary depending on the specific version of RouterOS and the RouterBoard model you are using:

1. Create the VLAN

First, you must create the VLAN on the device, assigning it a VLAN ID and associating it with a physical interface. This is done from the interface configuration menu.

/interface vlan
add name=vlan10 vlan-id=10 interface=ether2

This command creates a VLAN with ID 10 on the interface ether2 and names her vlan10.

2. Configure the Bridge (if necessary)

If you need multiple interfaces or VLANs to communicate with each other, you may need to configure a bridge and add the VLANs and/or physical interfaces to it.

/interface bridge
add name=bridge1

/interface bridge port
add bridge=bridge1 interface=ether2
add bridge=bridge1 interface=vlan10

This example creates a new bridge called bridge1 and add the interface ether2 and the VLAN vlan10 to bridge.

3. Assign IP Addresses (if necessary)

To allow communication over the VLAN, you may want to assign it an IP address.

/ip address
add address=192.168.10.1/24 interface=vlan10

This assigns the IP address 192.168.10.1 with a subnet mask of 255.255.255.0 (/24) to the VLAN vlan10.

4. Configure routing (if necessary)

Depending on your network configuration, you may need to configure static routes or use a dynamic routing protocol to allow traffic between different VLANs or between the VLAN and other networks.

Additional considerations

• RouterOS Model and Version: The specific steps and available options may vary depending on your RouterBoard model and RouterOS version. Be sure to consult the specific documentation for your hardware and software.
• VLAN Security: Consider implementing appropriate security measures, such as access lists and firewalls, to protect VLANs and control traffic between them.

VLANs are a powerful part of the network configuration on MikroTik RouterBoard devices, allowing great flexibility and control over network and traffic segmentation.
