JUNOS Cookbook

Preface

Over the past decade, network service providers have been adding high-performance Juniper Networks routers to their networks to run their IP backbones. With the recent introduction of smaller routers with the same basic functionality as the larger core routers, more people will be using Juniper Networks routers in their business networks and will need to learn how to configure and run the JUNOS software that runs on their routers. JUNOS Cookbook explains the design of the JUNOS software and provides recipes and guidelines for setting up common features that you need to configure and secure your Juniper Networks router.

For those of you who are familiar with Cisco IOS or other routers, you will find the JUNOS software and the design of the router hardware similar to the other routers in some ways, but very different in many ways. The initial design of the JUNOS software began in 1996, when the TCP/IP protocol suite was already mature and it was clear that this protocol suite was the only one needed for network devices to run on the Internet. Those involved in developing the original JUNOS software and router hardware all had previous experience designing similar products and were intent on building something better. Some of the JUNOS features that improve the router operation include:

Software modularity

The JUNOS software comprises several dozen processes, or daemons, rather than a single process, so you can stop a single process and restart it without having to reboot the ...
