JUNOS High Availability

What’s in This Book?

The ultimate purpose of this book is to be the single, most complete source for working knowledge related to providing high availability with Juniper Networks equipment. Though you may not find detailed configurations for all protocols and interfaces, you will find those tweaks and knobs that will provide high availability.

This book is divided into four parts, with a total of 25 chapters, and some general reference items put into the appendixes. The chapters are written by four different authors, although all of us tended to review each other’s work. You’ll be able to tell different voices in the writing styles, and we hope that is generally refreshing rather than a hindrance. Here is a detailed account of what’s in this book.

Part I

Chapter 1, High Availability Network Design Considerations

This chapter provides real-world perspective on the relative cost associated with making a network highly available and is the only nontechnical chapter in the book. It opens by describing a very simple, small enterprise network and then adds layers of redundancy, each designed to protect against a wider range of threats to continuity. The chapter concludes with a chart comparing the relative cost of the cumulative layers.

Chapter 2, Hardware High Availability

This chapter focuses on the foundation of Juniper Networks high availability: the hardware. It starts by discussing the divided architecture available on all systems and expands to the specific hardware redundancy features ...
