To register NSX-T Data Center network resources for VMware Cloud Director to use, add an external network backed by a tier-0 gateway.

Prerequisites

To create an external network that is backed by an NSX-T Data Center tier-0 gateway, first you must create a tier-0 gateway. You can create the tier-0 gateway in the NSX-T Manager UI or by using the NSX Policy API.

If you want to create an external network that is backed by a VRF gateway in NSX-T Data Center, you must also create a VRF gateway that is linked to the tier-0 gateway.

  • Create a tier-0 gateway in the NSX-T Manager UI .
    1. Log in with administrative privileges to the NSX-T Manager instance.
    2. Click Networking, click Tier-0 Gateways, and click AddGateway > Tier-0 .
    3. Enter a name for the Tier-0 router.
    4. Select a High Availability mode.
      Note: By default, the active-active mode is used. In the active-active mode, the traffic is load balanced across all members. In active-standby mode, an elected active member processes the traffic. If the active member fails, a new member becomes active.
    5. Select an existing NSX-T Edge cluster from the drop-down menu to back this tier-0 logical router, and click Save.
  • If you want to create an external network that is backed by a VRF gateway in NSX-T Data Center, create a VRF gateway that is linked to the tier-0 gateway.
    1. Log in with administrative privileges to the NSX-T Manager instance.
    2. Click Networking, click Tier-0 Gateways, and click Add Gateway > VRF.
    3. Enter a name for the VRF gateway.
    4. Select the tier-0 gateway to which to connect the VRF gateway.
    5. Click Save.

Procedure

  1. Log in to the VMware Cloud Director Service Provider Admin Portal.
  2. From the top navigation bar, select Resources and click Cloud Resources.
  3. In the left pane, click External Networks and click New.
  4. Select a site in which to register the new external network and click Next.
  5. On the Backing type page, select NSX-T Resources (Tier-0 Router), select a registered NSX-T Manager to back the network, and click Next.
  6. Enter a name and, optionally, a description for the new external network.
  7. Select a tier-0 gateway or a VRF gateway to connect to the external network, and click Next.
  8. Configure at least one subnet and click Next.
    1. To add a subnet, click Add.
    2. Enter the network Classless Inter-Domain Routing (CIDR) settings.
    3. (Optional) Enter the DNS settings.
    4. Configure a static IP pool by adding at least one IP range or IP address.
    5. Click OK.
    6. (Optional) To add another subnet, repeat steps Step a to Step e.
  9. Review the network settings and click Finish.

What to do next

Use the tier-0 gateway to create an uplink to the external network.
