Upgrading vCenter 7 to vCenter 8 is an article that shows, step by step, how to migrate the vCenter Server from version 7 to version 8. In our lab environment, we are using the following vCenter Server versions: From: vCenter Server 7.0 Update 3n (version 7.0.3.01600, build 21958406)To: vCenter Server 8.0 Update 2 (version 8.0.2.00000, build 22385739) Source: https://kb.vmware.com/s/article/2143838 Before Anything The upgrade process is a straightforward task. But, risks are involved and you need to be prepared to handle some problems and situations. We highly recommend you have a valid backup of the current vCenter Server. Additionally, you can…

Restoring a vCenter Server through backup is an essential recovery procedure that helps administrators bring back a vCenter Server Appliance using a valid file-based backup. This article demonstrates the complete restore process, from deploying a new vCenter Server Appliance to recovering the backed-up data. Before starting the restore operation, it is important to have a properly configured backup schedule on the vCenter Server. Without a valid file-based backup, this recovery method cannot be performed. VMware provides this backup approach to protect the vCenter configuration and data. In this example, we will use an existing vCenter Server backup to demonstrate how…

Performing tests on the NSX-T Overlay Networking is an article that shows how to perform some tests to validate the correct communication on the NSX-T Overlay Networking. Firstly, we have written an article explaining an Introduction to NSX-T:Introduction to NSX-T – DPC Virtual Tips Let’s talk a bit about the NSX-T Architecture So, first things first, let’s talk about the NSX-T Architecture. Basically, inside its architecture, we have some “layers” or “planes”. We will share a brief introduction of each one: As we showed, the Data Plane is the place where we have the Host Transport Node Devices (ESXi, for…

Configuring BGP Neighbor Between NSX-T and VyOS Router is an article that shows how to configure BGP to exchange routes between NSX-T T0 and VyOS Router. So, below we have our lab topology: As we can see in the above picture, our environment has an NSX-T with T0 and T1 Gateways and our NSX-T has an integration with both VyOS routers using the Border Gateway Protocol (BGP) for routing exchanges. We will show the VyOS configuration and the NSX-T configuration for providing the source device located in an NSX-T Segment to be able to communicate with the destination device located…

Basic VRRP Configuration on VyOS is an article that explains how to configure the VRRP protocol on the VyOS for router redundancy purposes. In this guide, we will configure a basic VRRP environment using two VyOS routers. We will create the VRRP configuration, validate the MASTER and BACKUP states, and test the virtual IP operation during normal and failover scenarios. Basically, What is VRRP? VRRP is an acronym for Virtual Router Redundancy Protocol. Is a computer networking protocol for providing IP gateway redundancy for IP networks. If you need to know more about it, please, access the below link:Virtual Router…

Performing Basic Configurations on the VyOS is an article that shows how to perform some basic and fundamental configurations on the VyOS router after the initial installation process. After installing VyOS, some fundamental configurations should be applied, such as changing passwords, configuring system identification, setting network interfaces, and enabling important services. These steps help create a functional and manageable router environment. First things first, we have written an article that explains the VyOS installation process. If you wish to check it, please access the below link:How to Install VyOS Router in a Lab Environment – DPC Virtual Tips Changing user…
