In this chapter, we learned how to use the devices in Packet Tracer to create VLANs, and to set up VTP to make their management easier. We also configured InterVLAN routing with both routers and layer 3 switches. So, by now, you'd be familiar with the SVIs of these layer 3 switches. Finally, we learned about the differences between normal switch-PC links and switch-switch links, which are also called trunks. The simulation mode of Packet Tracer is of immense help here, as it enables visualizing the packet flow in a VLAN environment.

The next and final chapter will show you how to create practical assessments in Packet Tracer so that you can distribute them and also use them to test your students or interview candidates.
