Cisco Aci Design Guide -

: The minimum recommended design for a stable fabric includes two spine nodes, two leaf nodes, and a cluster of three APICs . All leaves must connect to all spines, but they never connect to each other.

: Choose between Network-Centric design (mapping one VLAN to one EPG) for easier migration of legacy workloads, or Application-Centric design to group workloads by their functional role regardless of their subnet. Cisco Application Centric Infrastructure (ACI) Design Guide cisco aci design guide

Designing an effective Cisco Application Centric Infrastructure (ACI) fabric requires a shift from traditional device-by-device configuration to a centralized, policy-driven model. By leveraging a , ACI optimizes east-west traffic and simplifies scalability. Key Design Pillars : The minimum recommended design for a stable
