VRRP is a protocol that dynamically assigns responsibility for routers on a network. In a VRRP setup, one router is elected as the master, with the other routers acting as backups in case of the failure of the master router. In the event of an outage, once the down machine is fixed, it automatically becomes the master again, all without a network administrator having to reconfigure a large number of hosts. Using VRRP, network administrators can ensure that their networks stay up and running and eliminate costly downtime. Cisco, Juniper, Nortel and other networks use VRRP. Importantly, the book contains network configuration examples. Written by experts who helped design the protocol and who have real-world experience deploying it, VRRP is the only book specifically focused on VRRP.

"A detailed and clearly written book that is an invaluable resource to all VRRP users and implementers."
--Scott Bradner, Senior Technical Consultant, Harvard University
By employing the Virtual Router Redundancy Protocol (VRRP), administrators can ensure that their networks remain up and running, thereby eliminating expensive downtime. Using VRRP to avoid network outages is essential to building accessible, robust networks, and central to the implementation of successful disaster recovery models. Written by experts who contributed to the design of the VRRP protocol and participated actively in its deployment, VRRP: Increasing Reliability and Failover with the Virtual Router Redundancy Protocol is your best introduction to this powerful high-availability tool.
VRRP examines the general characteristics of the protocol and its usage. The emphasis is on translating the protocol specification into a tutorial form ideal for day-to-day users of VRRP. In addition to introducing the technology, this book provides an in-depth analysis, featuring extensive material on configuring, managing, and troubleshooting VRRP. Precursors to this protocol, such as Cisco's HSRP and DEC's IPSTP, are also discussed. Various vendor-specific extensions to VRRP--and their use in solving specific high-availability problems not addressed by VRRP--are also examined.
Network administrators and managers, protocol implementers, practicing professionals, researchers, and students exploring the area of high availability will gain a solid understanding of the core concepts of reliability and redundancy based on VRRP, as well as the particulars of the VRRP protocol and how to implement it.
The appendixes provide the necessary background for networking and TCP/IP, the full text of VRRP MIB, a study of actual VRRP implementations and an analysis of public-domain software available for VRRP over Linux, an overview of the VRRP state machine using SDL flowcharts and UML diagrams, and an analysis of the protocol through formal logic.
Ayikudy Srikanth is Director of Software Engineering at Crossbeam Systems, a company specializing in high-performance, highly available open platforms. He is a member of the VRRP working group in the Internet Engineering Task Force (IETF), and coauthored the VRRP over LAN emulation draft. He was the architect of the Nortel Bay series routers' VRRP and manager of the team that implemented it, and holds two patents related to VRRP extensions.
Adnan Adam Onart, former Director of Internetworking software at Fujitsu-Nexion, managed the implementation of the VRRP and the early high-availability strategy development for Nortel Networks' Contivity Extranet Switches group. He has conducted research on formal methods and published books on symbolic logic.
