In this chapter, we will take a step further toward understanding what happens inside OpenDaylight. It is a continuation of Chapter 4, Building a Virtual SDN Test Lab with Virtual Switches, where we learned about OpenDaylight's networking behaviors and basic communication between hosts in a Mininet environment.
We will continue with our OpenDaylight and Mininet virtual environments. However, we will go deeper into layer 2 switching and the Virtual Tenant Network (VTN) module of OpenDaylight; we'll go through this module in detail to understand how it works as it is a fundamental part of SDN networking.
We will use VTN to create VLANs and have a lab for isolating host traffic between different VLANs. VTN is one of the key modules of OpenDaylight. It has many features, such as virtual routers and bridges; we will cover them in more detail in Chapter 9, Building a Software...
