Layer 2 and Layer 3 switching.

Also written Layer 3 switch, L3 switch, Multilayer switch, Core switch.

What is the difference between a Layer 2 and a Layer 3 switch?

A Layer 2 switch forwards traffic by hardware address within one network; a Layer 3 switch also routes between networks. One Layer 3 core switch can route between dozens of separate virtual networks at wire speed without a standalone router. Buy Layer 2 at the edge where devices plug in, and Layer 3 at the core where those networks meet.
