![]() A particular kind of inter-VLAN routing, called “Router-On-A-Stick”, uses a trunk from the router to the switch to enable all VLANs to pass to the router. Trunks allow the traffic from multiple VLANS to travel over a single link, while keeping the VLAN identification and segmentation intact. ![]() ![]() VLAN trunks are used to span VLANs across multiple devices. Routers in VLAN topologies provide additional security and traffic flow management. Communication between VLANs requires a device operating at Layer 3 of the OSI model. In general, VLANs make it easier to design a network to support the goals of an organization. VLANs address scalability, security, and network management. Modern switches use virtual local-area networks (VLANs) to provide segmentation services traditionally provided by routers in LAN configurations.
