Starting with version 10.3.2, VMware Cloud Director supports non-distributed routing for organization VDC networks backed by NSX-T Data Center.
You can configure an NSX-T Data Center 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-T Data Center edge gateway.
You can use а non-distributed connection to connect a maximum of 9 organization VDC networks to a single NSX-T Data Center edge gateway.
Configuring DNS after NSX Data Center for vSphere to NSX-T Data Center Migration
If you are migrating your networking infrastructure from NSX Data Center for vSphere to NSX-T Data Center 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-T Data Center to also use its network gateway's IP address as a DNS server address.
To do that, after you set up your NSX-T Data Center 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-T Edge Gateway.
Configure an NSX-T Data Center Edge Gateway to Use Non-Distributed Routing
You can configure an existing NSX-T Data Center edge gateway to allow non-distributed routing by editing its general settings.
Prerequisites
-
Verify that you are a system administrator.
- Verify that the edge gateway for which you want to enable non-distributed routing is backed by NSX-T Data Center.
Procedure
- From the top navigation bar, select Resources and click Cloud Resources.
- In the left panel, click Edge Gateways.
- Click the NSX-T Data Center edge gateway for which you want to enable non-distributed routing.
- On the left, select the General tab, and click Edit.
- To enable non-distributed routing, toggle on the Allow Non-Distributed Routing option and click Save.
