Cisco Implementing Cisco Application Centric Infrastructure (300-620) Exam Preparation

ACI Packet Forwarding is a critical concept in Cisco's Application Centric Infrastructure (ACI) that describes how network traffic is routed and processed within the Application Policy Infrastructure Framework (APIC). It involves the intelligent management of data packets across the network, focusing on endpoint learning, bridge domain configurations, and efficient routing mechanisms. The core principle is to enable dynamic, policy-driven packet forwarding that adapts to application requirements and network topology.

In the ACI architecture, packet forwarding is not just about moving data from one point to another, but about creating a flexible, programmable network environment that can automatically adjust to changing application needs. This involves sophisticated mechanisms like endpoint tracking, Layer 2 and Layer 3 routing strategies, and intelligent proxy services that optimize network performance and security.
