This section allows you to create and configure 802.1Q VLANs (virtual LANs) on your router. VLANs allow you to separate your LAN into smaller groups for better bandwidth efficiency, network management, access control, and troubleshooting. Router ports can be configured as either untagged or tagged/trunk VLAN members for use on router ports or communication across multiple network switches with 802.1Q VLAN support. VLANs can be configured with different interface IP addresses to create multiple IP subnetworks along with the DHCP server function for dynamic IP address assignment. Inter-VLAN routing will allow communication between VLAN IP subnets. VLAN tags can also be assigned to specific wireless SSIDs/network names for VLAN communication across your wireless networks.
