VXLANs can use MCAST but most of the solutions are heading to point to point. ARP flooding between different hypervisors
Application Policy Infrastructure Controller (APIC): Implemented as a cluster of three boxes for fault‐tolerance and scalability benefits
ANP (Application Network Profile) is a policy that defines the requirements of the application in terms of network resources and how application components are connected.
Basically designed for cisco 9k but it can interact with other Nexus through 1000V
9k can work on NX-OS move (simple, enhanced, switch) or in ACI move, in combination with an APIC controller

- Unordered List ItemEPG (End Distribution Point). They are like port-groups or port-profiles, provide segmentation among workloads. EPGs contain one or more virtual and physical servers that require similar policy and connectivity. The Cisco ACI fabric allows you to define the communication path among EPGs, just as you do by stitching virtual lines between VLANs using IP routing and access control lists (ACLs). EPG as virtual extensible LAN (VXLAN)/Network Virtualization using Generic Routing Encapsulation (NVGRE) virtual network identifier (VNID)
- Unordered List ItemTenant: Within a tenant, you define one or more Layer 3 networks (VRF instances), one or more bridge domains per network, and EPGs to divide the bridge domains.
