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.
This document assumes that you have basic knowledge of IRF.
General restrictions and guidelines
When you set up and configure an IRF fabric, follow the restrictions and guidelines in this section.
This section provides only the basic restrictions and guidelines that ensure a successful IRF
deployment. For complete information, see IRF configuration guide for the switch.
Hardware requirements
An S6820 switch can form an IRF fabric only with switches in the same series.
Software requirements
All IRF member devices must run the same system software version.
Feature compatibility and configuration
restrictions
Make sure the feature settings in
are the same across member devices.
