Routing switch is mainly used in a network like LAN. It is a device that combines the functions of a switch, which forwards data by looking at a physical device address, and a router, which forwards packets by locating a next hop address.

It has three forms of layer 3 connectivity. This is technology that was implemented by local-area network (LAN) vendors to use switches to offset performance and latency problems with older routers; Fully proprietary implementations: These implementations are falling by the wayside in campus LANs due to their complexity, their need for constant management and their divergence from industry direction.
