and This name-space translation function should be performed at line rate to avoid negatively affecting the performance of intersite communication. To achieve this, you must use specific hardware for the spine nodes deployed in the Cisco ACI Multi-Site architecture: only the Cisco Nexus® EX platform (and newer) generation of spine switches are supported in a Multi-Site deployment.
