Extending Overlay Segments to VLAN via the VMware NSX Edge Bridge

Reading Time: 8 minutes

I’ve worked with many customers over the years who are new to VMware NSX. This generally means a full design and deployment of NSX, but to be honest, a) that’s the easy bit and b) it doesn’t give the customer much in the way of immediate value. After all, all we’ve done is deploy a software-defined networking platform and generally peered it with the physical environment.

The value begins once the Customer’s workload is actually housed on an NSX Segment. This is where we begin discussing workload migrations from physical VLANs/VDS port groups to NSX Overlay Segments. ‘Easy’ you say, ‘just migrate the virtual machines and re-IP, right’? That’s one option, however, what if the Customer has thousands of VMs? What if these VMs host mission-critical applications or applications which are prone to issues following re-IPing? Sometimes this option just isn’t feasible.

The best solution for this Customer might be to migrate workloads and retain IP addressing. We can achieve this by migrating the entire physical network into VMware NSX, however, we can also achieve this by creating a VMware NSX Edge Bridge, which effectively creates a layer-2 extension between a physical VLAN and an NSX Overlay Segment.

In this article, we will detail a number of migration scenarios before detailing the process of deploying and configuring a layer 2 extension via NSX Edge Bridge.

VMware NSX-T Data Center Migration – Part 1 – Deploy Manager Appliance

Reading Time: 6 minutes

Welcome to the first in a new series of articles detailing the migration process of VMware NSX Data Center for vSphere to NSX-T Data Center. The migration to NSX-T will be split into three steps:

  • Part 1 (this article) – Deploy NSX -T Data Center Manager Appliance, and prepare this new NSX-T environment for the migration of NSX Data Center for vSphere by adding a Compute Manager, and creating an IP Pool for Edge Tunnel End Points (TEPs).
  • Part 2 – Prepare NSX Data Center for vSphere for migration to NSX-T, including ESXi host, vSphere Distributed Switch, and NSX-V pre-flight checks (VXLAN, VTEP, Controllers, Edge Services Gateways).
  • Part 3 – Migrate NSX Data Center for vSphere to NSX-T Data Center.

Note – In this article, the process of deploying the VMware NSX-T Data Center Manager Appliance can be considered the same as whether you are a) deploying into a greenfield environment void of any NSX, or b) migrating NSX Data Center for vSphere to NSX-T.
