his booklet continues teaching the core concepts begun in the first volume, Day One: Applying Junos Operations Automation. Event automation instructs Junos of actions to take in response to system events through event policies and event scripts. Use event automation in your network to:Speed time-to-resolve to reduce the downtime and cost of eventsExplain where to use the different Junos script typesMinimize the impact of events on network operationsAutomate time-of-day configuration changes

This revised and expanded edition shows you step-by-step how to implement high-density, high-speed Layer 2 and Layer 3 Ethernet services, using Router Engine DDoS Protection, Multi-chassis LAG, Inline NAT, IPFLOW, and many other Juniper MX features. This second edition was written by a Senior NOC engineer, whose vast experience with the MX Series is well documented. Each chapter covers a specific Juniper MX vertical and includes review questions to help you test what you’ve learned. This edition includes new chapters on load balancing and vMX—Juniper MX’s virtual instance. Work with Juniper MX’s bridging, VLAN mapping, and support for thousands of virtual switches Examine Juniper MX high-availability features and protocols Use Trio Chipset’s load balancing features for different types of traffic Explore the benefits and typical use cases of vMX Add an extra layer of security with Junos DDoS protection Create a firewall filter framework that applies filters specific to your network Discover the advantages of hierarchical scheduling Combine Juniper MX routers, using a virtual chassis or Multi-chassis LAG Install network services such as Network Address Translation (NAT)
Administer, configure, and monitor Junos in your organization About This Book Get well acquainted with security and routing policies to identify the use of firewall filters. Learn to provide end-user authentication and protect each layer in an enterprise network. A recipe-based guide that will help you configure and monitor Junos OS and basic device operations. Who This Book Is For This book targets network engineers, developers, support personals, and administrators who are working on devices running Junos OS and are looking at automating their organisation's operations. Some understanding about Junos would be necessary What You Will Learn Start using NETCONF RPC standard and understand its usefulness in programming JUNOS Write SLAX scripts to respond to events in the JUNOS environment Automate JUNOS with PyEZ Deal with events in the JUNOS environment, and writing response handlers to deal with them Make the most of automation technologies to help with maintenance and monitoring of JUNOS Use the Ansible framework to extend the automation functionality of Junos In Detail The JUNOS Automation Cookbook is a companion guide for the complex field of automating tasks on JUNOS devices. With a foundation in industry-standrd XML, JUNOS provides an ideal environment for programmatic interation, allowing you to build upon the capabilities provided by Juniper, with your own original code. You will begin by learning about, and setting up, the industry-standard NETCONF remote procedure call mechanisms on your device. After initial setup, you'll walk through SLAX - Juniper's foundation scripting language - for manipulating XML representations of JUNOS concepts and elements. You'll learn how to write your own SLAX scripts to customise the operating environment, and also how to write proactive event handlers that deal with situations as they happen. You'll then delve into PyEZ - Juniper's bridging framework to make automation accessible to Python code - allowing you to build automation applications in the popular scripting language. You'll witness some examples of how to write applications that can monitor configuration changes, implement BGP security policies and implement ad-hoc routing protocols, for those really tricky situations. You'll also leaarn how asynchronous I/O frameworks like Node.js can be used to implement automation applications that present an acceptable web interface. Along with way, you'll explore how to make use of the latest RESTful APIs that JUNOS provides, how to visualize aspects of your JUNOS network, and how to integrate your automation capabilities with enterprise-wide orchestration systems like Ansible. By the end of the book, you'll be able to tackle JUNOS automation challenges with confidence and understanding, and without hassle. Style and Approach A guide that will cover all the automation tools along with steps on leveraging these tools
Despite the explosion of networking services and applications in the past decades, the basic technological underpinnings of the Internet have remained largely unchanged. At its heart are special-purpose appliances that connect us to the digital world, commonly known as switches and routers. Now, however, the traditional framework is being increasingly challenged by new methods that are jostling for a position in the “next-generation” Internet. The concept of a network that is becoming more programmable is one of the aspects that are taking center stage. This opens new possibilities to embed software applications inside the network itself and to manage networks and communications services with unprecedented ease and efficiency. In this edited volume, distinguished experts take the reader on a tour of different facets of programmable network infrastructure and applications that exploit it. Presenting the state of the art in network embedded management and applications and programmable network infrastructure, the book conveys fundamental concepts and provides a glimpse into various facets of the latest technology in the field.
How can you grow and maintain a reliable, flexible, and cost-efficient network in the face of ever-increasing demands? With this practical guide, network engineers will learn how to program Juniper network devices to perform day-to-day tasks, using the automation features of the Junos OS. Junos supports several automation tools that provide powerful solutions to common network automation tasks. Authors Jonathan Looney and Stacy Smith, senior testing engineers at Juniper, will help you determine which tools work best for your particular network requirements. If you have experience with Junos, this book will show you how automation can make a big difference in the operation of your existing network. Manage Junos software with remote procedure calls and a RESTful API Represent devices as Python objects and manage them with Python’s PyEZ package Customize Junos software to detect and block commits that violate your network standards Develop custom CLI commands to present information the way you want Program Junos software to automatically respond to network events Rapidly deploy new Junos devices into your network with ZTP and Netconify tools Learn how to use Ansible or Puppet to manage Junos software
