To reapply the data center group network configurations and ensure that all participating virtual data centers are active, you can synchronize the data center group.

Note: During the data center group synchronization process, the data center group becomes unavailable for a few seconds, because the universal router synchronizes in NSX.


This operation requires the System Administrator role or a role with the VDC Group: Configure VDC Group right published to the organization.


  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. Click Sync data center group.
  4. To confirm, click OK.
