Overview of this book

VMware NSX is a platform for the software-defined data center. It allows complex networking topologies to be deployed programmatically in seconds. SDNs allow ease of deployment, management, and automation in deploying and maintaining new networks while reducing and in some cases completely eliminating the need to deploy traditional networks. The book allows you a thorough understanding of implementing Software defined networks using VMware’s NSX. You will come across the best practices for installing and configuring NSX to setup your environment. Then you will get a brief overview of the NSX Core Components NSX’s basic architecture. Once you are familiar with everything, you will get to know how to deploy various NSX features. Furthermore, you will understand how to manage and monitor NSX and its associated services and features. In addition to this, you will also explore the best practices for NSX deployments. By the end of the book, you will be able to deploy Vmware NSX in your own environment with ease. This book can come handy if you are preparing for VMware NSX certification.

Configuring VXLAN

Before we jump into configuring transport zones, let's look at configuring VXLAN, which is part of preparing a cluster. VXLAN allows for layer 2 logical switching across hosts and can span multiple layer 3 domains. VXLANs are configured on a per-cluster basis, where each cluster that is to participate in NSX is mapped to a virtual distributed switch (VDS). All hosts in that cluster are then enabled for logical switches.


If you only plan to use the distributed firewall feature of NSX, you do not need to configure VXLAN transport layer.

When you configure VXLAN networking, you must provide a vSphere distributed switch, a VLAN ID, an MTU size, an IP addressing mechanism (DHCP or IP pool), and a NIC teaming policy.

Jumbo frames are necessary, so the MTU for each switch must be set to 1550 or higher. By default, it is set to 1600.

To configure VXLAN, follow these steps:

  1. Navigate to Home | Networking & Security | Installation and select the Host Preparation tab.
  2. Click Not Configured...
