The Mi Router AX9000 supports VLAN.
A VLAN (Virtual Local Area Network) is a logical subgroup within a physical network that allows devices to communicate as if they were on the same physical network segment, even if they are actually located on different network segments. VLANs are used to improve network performance, increase security, and simplify network management.
VLANs can create separate guest networks, allowing you to access the internet without accessing internal resources. By isolating devices and controlling broadcast domains, VLANs help organizations create flexible, secure, and efficient network environments.
