During failover of the SDDC management applications to Region B, the universal NSX components for dynamic routing are deployed in Region B. If a site failure occurs in Region B, the management applications might lose connectivity if you fail them back to Region A right away. Deploy and configure a control VM for the universal dynamic logical router sfo01m01udlr01 in Region A to restore dynamic routing for the management applications.
