APICACI SpineNodesInsiemeFabricControllerACI LeafNodes ACI Fabric provides:‒Decoupling of endpoint identity, location, and associated policy, all of which are independent from the underlying topology‒Full normalization of the ingress encapsulation mechanism used: 802.1Q VLAN, IETF VXLAN, IETF NVGRE‒Distributed Layer 3 gateway to ensure optimal forwarding for Layers 3 and 2‒Support for standard bridging and routing semantics without standard location constraints (any IP address anywhere)‒ Service insertion and redirection‒Removal of flooding requirements for IP control plane (ARP, GARP)

Each node will beassigned loopback IPaddress(es) advertisedthrough IS-ISIP fabric withintegratedoverlayIP un-numbered40 Gb links ACI Fabric is based on an IP fabric supporting routing to the edge with an integrated overlay for host routing‒ All end-host (tenant) traffic within the fabric is carried through the overlay The fabric is capable of supporting an arbitrary number of tiers and/or partial mesh if required Why choose an integrated overlay?‒ Mobility, scale, multi-tenancy, and integration with emerging hypervisor designs‒ Data traffic can now carry explicit meta data that allows for distributed policy (flow-level control without requiring flow-levelprogramming)APIC
