Mikrotik Q In Q Vlans

Q-in-Q (aka VLAN stacking) is a protocol used in computer networking to allow multiple VLAN tags to be encapsulated within another VLAN tag. This enables network administrators to create hierarchical VLAN structures that can be used to isolate traffic between different departments or customers on a shared network.

In MikroTik routers, Q-in-Q can be configured using the "vlan" and "interface" commands in the Terminal console or the Winbox GUI.
