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.


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.


  1. In the top navigation bar, click Networking and then click 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.


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.
