... Here we are, at the final part of our series on how to install a virtual NSX lab. With our vSphere infra, NSX Manager, and NSX Control Cluster installed, we can now move to the NSX dataplane. NSX Dataplane The process for data plane installation is based upon the NSX

Previously we installed the vSphere infra, and the NSX Manager. Now we will install the NSX control plane. Let's continue... NSX Control Plane We will now deploy the NSX Control Cluster. The control cluster will be 3 x VMs deployed by the NSX manager onto the Edge cluster.

Within the previous part to our series, we installed the vSphere infra. We will now deploy the NSX manager and associate it to our vCenter. NSX Manager Deploy Within vCenter deploy the NSX Manager OVF, during the install using the following settings. DNS Server list 172.29.236.139 Domain

What is Micro-Segmentation? When it comes to SDN micro-segmentation is one of the biggest use cases/features that it has to offer. But what is micro-segmentation? In its purest form, Micro-Segmentation is a security technique that further isolates workloads/segments, allowing for finer-grained security controls to be applied. Traditionally, network

Within this post, we will show you how to build a virtualized NSX SDN lab. Our lab will be loosely based around the VMware NFV 2.0.1 Reference Architecture. For those of you who haven't worked with the VMware NFV reference architecture, it consists of a set

Introduction The controller cluster in the NSX platform is the control plane component responsible for managing the hypervisor switching and routing modules. This includes the logical switches and VXLAN overlay. Due to the centralized, decoupled model of the controller, it provides the ability to reduce broadcast traffic, in turn negating

Overlay networks decouple the network services from the underlying physical network infrastructure. This is achieved by running a virtual network onto of the underlay via the use of network encapsulation. There are 2 main types of overlay solutions - Network-Centric and Host-Centric Overlays. Network-Centric With Network-Centric overlays, the network device

When BUM (Broadcast, Unknown unicast and Multicast) traffic is sent out from a VM, the source VTEP must replicate this traffic out to the other VTEPs via VXLAN encapsulation. NSX provides 3 modes of replication - Multicast, Unicast and Hybrid. Multicast Multicast replication utilizes L2 (IGMP) and L3 (PIM) multicast
