VMware Cloud Director supports non-distributed routing for organization VDC networks backed by NSX.

You can configure an NSX edge gateway to allow non-distributed routing and you can connect routed organization VDC networks directly to a tier-1 service router, forcing all VM traffic for a specific network through the service router.

You can use the non-distributed routing feature to create firewall rules and isolate east-west traffic between organization VDC networks that are connected to the same NSX edge gateway.

You can use а non-distributed connection to connect a maximum of 9 organization VDC networks to a single NSX edge gateway.

Configuring DNS after NSX Data Center for vSphere to NSX Migration

If you are migrating your networking infrastructure from NSX Data Center for vSphere to NSX and you were using your organization VDC network gateway address as a DNS server address, you can use non-distributed routing to configure your organization VDC network that is backed by NSX to also use its network gateway's IP address as a DNS server address.

To do that, after you set up your NSX edge gateway and your organization VDC network for non-distributed routing, create a DNAT rule that points to the edge gateway's DNS service and enter the DNS server's IP address in the Applied to text box. See Add an SNAT or a DNAT Rule to an NSX Edge Gateway in the VMware Cloud Director Service Provider Admin Portal.

Configure an NSX Edge Gateway to Use Non-Distributed Routing in VMware Cloud Director

In VMware Cloud Director, you can configure an existing NSX edge gateway to allow non-distributed routing by editing its general settings.

Prerequisites

  • Verify that you are logged in as a system administrator.

  • Verify that the edge gateway for which you want to enable non-distributed routing is backed by NSX.

Procedure

  1. From the top navigation bar, select Resources and click Cloud Resources.
  2. In the left panel, click Edge Gateways.
  3. Click the NSX edge gateway for which you want to enable non-distributed routing.
  4. On the left, select the General tab, and click Edit.
  5. To enable non-distributed routing, toggle on the Allow Non-Distributed Routing option and click Save.

What to do next

Deactivate distributed routing during the creation of an organization VDC network that is connected to this edge gateway. See Add a Routed Organization Virtual Data Center Network in the VMware Cloud Director Tenant Guide.
