To support dynamic routing in Region B before you start disaster recovery from Region A, configure the universal distributed logical router sfo01m01udlr01 and NSX Edges lax01m01esg01 and lax01m01esg02. This ensures the management components of the SDDC continue to communicate using optimal routes in a fault-tolerant network.
