Chapter 12
Bits and Bytes of ACI Forwarding
At its core, ACI is a data center technology that provides a fully managed fabric with forwarding optimizations and performance enhancements. Using VXLAN, traffic can be tunneled to any node in the fabric, ensuring that workloads can exist anywhere without introducing complexity. This chapter describes how forwarding inside the fabric works. When you know how a packet moves through the ACI fabric, you can explore the details of the iVXLAN header, how multicast distribution trees (MDTs) are built, and what control plane protocols exist. This chapter presents forwarding scenarios that demonstrate how packets move inside the ACI fabric.
In this chapter, you will learn the following:
