In the case of failback, because of the failure in Region B, dynamic routing in Region A is not available. Deploy a Control VM for the universal dynamic logical router sfo01m01udlr01 in Region A to recover dynamic routing in the environment. You then re-configure the recovered Control VM to provide dynamic routing for the SDDC management applications that are failed back.
