To support dynamic routing in Region A before you initiate disaster recovery from Region B, you configure the universal distributed logical router sfo01m01udlr01, and NSX Edge nodes sfo01m01esg01 and sfo01m01esg02. This configuration ensures that the management components of the SDDC continue to communicate using optimal routes in a fault-tolerant network.
