Configuring Layer 3 Routing on EtherWAN Switches

In a previous article we discussed the differences between Layer 2 and Layer 3 switches. Layer 3 switches now often support unicast and multicast routing, and even the Virtual Router Redundancy Protocol (VRRP). Depending on the size, configuration, presence of multicast devices, and external connections, different routing methods may be needed.

Layer 2 and Layer 3 Switches Explained

For decades there were switches, and then there were routers. It was obvious that switches performed switching, and routers did the routing. But in the past few years, there has been the emergence of “Layer 3 switches,” which has raised questions for some about the difference between Layer 2 switch and Layer 3 switch . i.e., the differences between switching and routing, and which type of switch should be deployed in which situations.
