In last post of this series we briefly looked what is VXLAN (In actual it’s an ocean of knowledge in itself) and also we configured VXLAN on our cluster/hosts.

In this post we will be talking about Logical switching and we will see how to create that and will cover prerequisites part as well.

Let’s start with introduction to Logical Switching.

What is Logical Switching?

Functionality of a Logical switch is very similar to that of a physical switch i.e they allow isolation of applications and tenants for security purpose. A logical switch when deployed, creates a broadcast domain to allow isolation of the VM’s running in infrastructure.… Read More

In last post of this series we saw how to prepare Esxi host and Cluster for NSX. In this post we will be talking little bit about VXLAN, what are its benefits and how to configure VXLAN on Esxi hosts.

Lets start our discussion with what is VXLAN.

Virtual Extensible LAN (VXLAN) is an encapsulation protocol for running an overlay network on existing Layer 3 infrastructure. An overlay network is a virtual network that is built on top of existing network Layer 2 and Layer 3 technologies to support elastic compute architectures.

In VXLAN the original layer 2 frame is encapsulated in a User Datagram Protocol (UDP) packet and delivered over a transport network. This technology provides the ability to extend layer 2 networks across layer 3 boundaries and consume capacity across clusters.… Read More
