The next release of Terraform’s NSX-T provider will add support for the NSX-T policy API. I know many people (including myself) have been waiting for this so it’s kind of a big thing within that space. While the new NSX-T provider is not released yet (it’s still being tested), the source code is available on…
With NSX-T logical networking the Tier-0 uplinks become the central passage for all of the North-South traffic—i.e., traffic between the NSX-T logical networks and the physical network. A critical point in the NSX-T data plane and one that we might want to place under a magnifying glass from time to time. In this short article…
Welcome back! We’re in the process of building an NSX-T Edge – FRRouting environment. In part 1 we prepared the FRR routers by doing he following: Installed two Debian Linux servers Installed VLAN support Enabled packet forwarding Configured network interfaces Installed and configured VRRP Installed FRRouting In this second part we will first deploy the…
Until recently I always used pfSense with the OpenBGPD package as the NSX-T Edge counterpart in my lab environment. It’s quick and easy to set up and works well enough. But pfSense is not what I typically find in a customer’s production environment. I started to investigate other virtualized “top-of-rack solutions” for the lab that…
Now that I started studying for the AWS Certified Advanced Networking – Specialty I have to learn pretty much everything about AWS networking. Naturally VPN is a part of that. When it comes to AWS VPN the most common use case is establishing secure Site-to-Site connections between the customer’s data center and a Virtual Private…
A while back Dumlu Timuralp published an excellent guide on integrating NSX-T 2.5 with K8s. If you haven’t read it already I strongly recommend that you have a look at it. The guide goes through every step of configuring the integration and does a great job explaining the architecture and components that make up this…
Like any other firewall the NSX-T Distributed Firewall (DFW) consumes memory and CPU. Unlike other firewalls the DFW’s resource consumption is distributed, taking place on the transport nodes where the workloads it protects reside. Memory allocation An ESXi transport node allocates a fixed amount of memory for the different DFW components. The amount of memory…
After receiving a couple questions about the NSX-T firewall policy locking feature, I decided to write a short blog post about it. The purpose of locking a firewall policy The easy part first. As explained in the official NSX-T documentation we lock a firewall policy to prevent multiple users from editing the same section. Locks…
With every new release of NSX-T interesting features are added to the platform. Take failure domain for example. Introduced in version 2.5, failure domain adds another layer of protection for the centralized services running on Tier-1 Gateways. It basically facilitates a rack aware placement mechanism for the Tier-1 service router (SR) components. In today’s article…
Imagine this, you’ve been tasked with implementing micro-segmentation in your vSphere environment. You just deployed and configured NSX-T and the next step is to migrate VMs from their VDS port groups to N-VDS segments. You fire up the vSphere Client and expand the VDS to have a look at the current situation: It’s pretty bad.…
