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.
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.
