You can use network simulators or emulators on your computer to create, configure, and modify network topologies. Some of the most common ones include:

  • GNS3 - a free open source emulator
  • EVE-NG - a free open source emulator
  • Cisco VIRL - an older version of Cisco's online emulator
  • Cisco CML - an online emulator, the successor to VIRL
  • Cisco Packet Tracer - Cisco's simulator software package

Alternatively you can purchase switches and routers and create a lab from real physical equipment. This can get expensive, although older used devices are available for purchase at very low prices.
