You can create and configure a virtual data center group backed by NSX Data Center for vSphere with a fault domain egress configuration, where you configure an edge gateway that acts as an active egress points for each network fault domain in the group. Standby egresses cannot be created in a data center group with a fault domain egress configuration.

Prerequisites

Verify that you are logged in as a System Administrator or a role with the VDC Group: Configure VDC Group right published to the organization.

Create a Data Center Group Backed by NSX Data Center for vSphere with a Fault Domain Egress Configuration in the VMware Cloud Director Tenant Portal

You can group between 1 and 16 virtual data centers in a data center group backed by NSX Data Center for vSphere with a fault domain egress configuration.

Prerequisites

The system administrator enabled the target virtual data centers for cross-virtual data center networking.

Procedure

  1. From the primary left navigation panel, select Networking, and from the page top navigation bar, select the Data Center Groups tab.
    The list of data center groups appears.
  2. Click New.
  3. Enter a name and, optionally, a description for the new data center group.
  4. Select Egress Points per Fault Domain and click Next.
  5. On the Participating VDCs page, select additional data centers for the new data center group, and click Next.
    The Data Centers page contains a list of the VDCs that the system administrator has enabled for cross-virtual data center networking.
  6. Review the data center group details and click Finish.

Results

The newly created virtual data center group is listed in the Data Center Groups view.

Add an Egress Point for a Fault Domain in the VMware Cloud Director Tenant Portal

To connect the virtual data centers from a network fault domain in a data center group backed by NSX Data Center for vSphere to the Internet, you must add an egress point to this network fault domain. You can add an egress point to each network fault domain in the data center group. Stand-by egress points are not supported in a data center group with a fault domain egress configuration.

Prerequisites

Apart from the edge gateways that are in use as egress points in this data center group, you must have at least one unused edge gateway in any of the participating virtual data centers.

Procedure

  1. From the primary left navigation panel, select Networking, and from the page top navigation bar, select the Data Center Groups tab.
    The list of data center groups appears.
  2. Click the target data center group.
    The Network Topology view for this data center group opens. The diagram of the current network topology displays the participating VDCs with their network fault domains, the egress points, if configured, and the traffic routes.
  3. On the diagram of the network topology, click the target network fault domain.
    Network fault domains are represented with solid lines and their names at the bottom of the diagram.
    The selected fault domain is marked in blue.
  4. Click Add egress point.
    The Add Active Egress Point page opens providing a list of the edge gateways that belong to the participating virtual data centers.
  5. Select the edge gateway that you want to act as an egress point for this fault domain, and click Add.

Results

BGP routes are configured on the edge gateway representing the egress point and the universal router of the network fault domain. Existing routes on the edge gateway are not affected.

The diagram of the network topology is updated with the newly added egress point. The traffic from the virtual data centers in the network fault domain to the Internet is represented with a continuous blue line.
