JUNOS High Availability

Network outages can be deadly, whether your network is a complex carrier network or just a few machines supporting a small enterprise. "JUNOS High Availability" will help you build reliable and resilient networks that include Juniper Networks devices. With this book's valuable advice on software upgrades, scalability, remote network monitoring and management, high-availability protocols such as VRRP, and more, you'll have your network uptime at the five nines, or 99.999 percent of the time. Instead of focusing on 'greenfield' designs, the authors explain how you can intelligently modify multi-vendor networks. By looking at how existing protocols and platforms are currently used, and adapting new devices to them, you can deploy continuous systems even when reporting scheduled downtime.With this book, you will learn how to: upgrade routing engine software painlessly; manage network equipment with Best Common Practices; integrate routers and switches from multiple vendors in a mature network; enhance scalability by adjusting network designs and protocols; combine the IGP and BGP networks of two merging companies; perform network audits; identify JUNOScripting techniques to maintain high availability; secure network equipment against breaches, and contain DoS attacks. Automate network configuration through specific strategies and tools. "JUNOS High Availability" will save you time and money no matter what kind of network you have. Written by four system engineers with vast expertise in maintaining continuous systems, this book is a core part of the Juniper Networks Technical Library.
