In this legacy approach, inter-VLAN routing is performed by connecting different physical router interfaces to different physical switch ports. Each interface had to be connected to a separate network and configured with a distinct subnet. Historically, the first solution for inter-VLAN routing relied on routers with multiple physical interfaces. Regardless of the device used, the process of forwarding network traffic from one VLAN to another VLAN using routing is known as inter-VLAN routing. Any device that supports Layer 3 routing, such as a router or a multilayer switch, can be used to perform the necessary routing functionality. With the large number of VLANs possible on these switches, static routing is insufficient.Ī VLAN is a broadcast domain, so computers on separate VLANs are unable to communicate without the intervention of a routing device. While Layer 2 switches are gaining more IP functionality, such as the ability to perform static routing, these switches do not support dynamic routing. However, Layer 2 switches have very limited IPv4 and IPv6 functionality and cannot perform the routing function of routers.

Layer 2 switches, such as the Catalyst 2960 Series, can be configured by a network professional with over 4,000 VLANs. VLANs are used to segment switched networks.
