Layer 3 switches were conceived as a technology to improve
on the performance of routers used in large local area
networks (LANs) like corporate intranets. The key difference
between Layer 3 switches and routers lies in the hardware
technology used to build the unit. The hardware inside a
Layer 3 switch merges that of traditional switches and
routers, replacing some of a router's software logic with
hardware to offer better performance in some situations.
Layer 3 switches often cost less than traditional routers.
Designed for use within local networks, a Layer 3 switch
will typically not possess the WAN ports and wide area
network features a traditional router will always have.
To answer the question, one needs to consider the
environment where the equipment will be deployed.
