Troubleshooting Edge Gateway High Availability

Yesterday I was working on Edge Services Gateway in my Lab and deployed the edge gateway in HA mode. Soon after the deployment when I checked the HA status from vCenter, it reported status as Down

edge-ts-0

To counter any UI bug which might be reporting HA status as down (as this was a brand new deployment), I decided to check the HA status by logging onto edge vm’s directly.

On checking for the HA status on the VM, below message was displayed

Highavalibity healthcheck server is stopped

I did a search on google for this message and didn’t get much results. Then I checked the Admin guide for NSX and came to know the fact that you should have at least one vNIC configured as High availability traffic flows on one of the internal interface.

By design the edge High Availability Service will only kick in once the first Internal vNIC has been added and configured. … Read More

Learning NSX-Part-9-Edge Services Gateway

In last 2 post of the series we discussed about Distributed Logical Router. Moving forward in NSX learning series, we will look into what is Edge Service Gateway and will discuss on when to use edge gateway. We will look into deploying ESG and configuring it and then finally some touch down points on monitoring Edge gateways.

8: Installing Distributed Logical Router

In VMware NSX for vSphere there are two different types of NSX routers which can be deployed in virtual network infrastructure.

  1. The NSX Edge Services Router (ESR)
  2. The NSX Distributed Logical Router (DLR)

Both the ESR and DLR can run dynamic routing protocols, or not.… Read More

Learning NSX-Part-8-Installing Distributed Logical Router

In last post of this series we discussed about distributed logical router and went through some important terms and terminologies. In this post we will jump into lab and will deploy logical distributed router.

7: Distributed Logical Router Tidbits

Before jumping into deploying distributed router, I want to stress on the fact that your logical switches be ready. What i mean here since you wanna test routing between 2 or more different subnets, you should have logical switches ready in place and should have some live VM’s attached to it.

In my lab I have 3 logical switches created for this purpose.

Learning NSX-Part-7-Distributed Logical Router Tidbits

In last post of this series we discussed about Logical Switching and understood when do we use logical switching. Also we deployed our first logical switch and moved a VM over to the newly created switch.

In this post we will discuss about Distributed Logical Router and look at the terms and terminology associated with it. We will not be diving into lab in this post as I intend to this in next post of this series

Overview

Physical Routers are the building block of any network infrastructure. They are essential for building a working network topology. As we know Routers comes into picture when we need communication between 2 different subnets.… Read More

Delete Stale Org Networks and Edge Gateway from vCloud Director

Today while working in production, I came across an issue where the edge VM’s backing the edge gateway were not present in vCenter (no idea how they got deleted).

Due to this I was not able to delete the Org network from vCD. Any attempt to delete the Org network was failing with error
