  • Page 3: Introduction

    Introduction This document provides examples for setting up IRF fabrics and configuring link aggregation and routing on the IRF fabrics. Prerequisites The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

    • The link aggregation must use dynamic aggregation mode. • The link aggregation must have a minimum of one member link from each member chassis. • If the intermediate device is also an IRF fabric, you must assign the two IRF fabrics different domain IDs for correct split detection.
