![]() ![]() This type of CISCO network switches support routing protocols. It acts as a switch to connect devices that are on the same subnet or virtual LAN. This type of layer helps you to combine the functionality of a switch and a router. ![]() A client computer needs a default gateway for layer 3 connectivity to any remote subnets. Difference between Layer 2 and Layer 3 SwitchesĪ Layer 3 switch is a switch that performs routing functions in addition to switching.In this networking tutorial, you will learn: Instead, they should look at the frame’s hardware addresses, which helps you decide what action needs to take like forward, flood, or drop it. Layer 2 ethernet switches are faster compared to routers, as they do not take much time for evaluation at the network layer header information. It builds tables for the transfer of frames among systems. They interconnect networks at layer 2, mostly at the MAC sub-layer, and operate as bridges. Layer 2 CISCO switches are similar to bridges. They help to break up large size collision domain into separate smaller ones. Switches and bridges are mostly used for Layer 2 switching. It is the process of using devices and MAC addresses on a LAN to segment a network. The term Layer 2 is adopted from the Open System Interconnect ( OSI) model, which is a reference model for explaining and describing network communications.
