When the corporate grows, the network grows. Network of SMB was usually designed as a flat network, that is, one single subnet for connecting all the network devices of servers, PCs, printers, etc. The most common problem for these SMB networks is the shortage of usable IP addresses when the number of nodes grow beyond the available IP for the subnet.
It is also incapable to segment the network and apply network access control between different departments or functional groups when network security is a concern.
Nowadays the network is designed on a Layer 3 basis, with a L3 capable switch acting as the network core, such as Cisco Catalyst 3850, and route the data packets between network segments. The following diagram shows a classic network setup for SMB.
