OSPF and IS-IS: Choosing an IGP for Large-Scale Networks: Choosing an IGP for Large - Scale Networks Paperback – Illustrated, 1 November 2005

Great book from one of the best Cisco instructors. Quality of the paper, not so great

Doyle does an excellent job of starting from ground zero and building up...Included are points of interest and concerns that a senior level net engineer might think of but someone beginning or intermediate may not quickly consider...I also like the fact that he compares and contrasts the two protocols side by side in the same section, not doing the 1/2 the book on ospf, then the other half on is-is or chapter specific. Each chapter will talk about a particular subject (say message types) and in the chapter he'll go through both protocols.Doyle also points out differences in IOS vs JUNOS which is real nice as well.Chapters are:I Roots of Link State Protocols: brief history of arpanet (not like IRA 2nd edition either, IRA = Internet Routing Architectures)II Link State Basics: He does cover DV basics as well to have something to contrast to...III Message TypesIV Addressing, Neighbor Discovery, AdjacenciesV FloodingVI Link State Database SynchronizationVII Area DesignVIII ScalingIX Security/ReliabilityX ExtensibilityXI MPLS Traffic EngineeringXII IV6XIII Multi-Topology RoutingMuch better than the Cisco Press books and I have all three:Cisco Press, OReilly, and Addison Wesley...Although Doyle's TCP/IP Vol II is CP

I came across this book by chance on Amazon. Seeing Jeff Doyles name I had to read it. I have read Jeff Doyles previous work such as Routing TCIP and Juniper Network Routers. Both books played a strong role in building my foundations in advanced routing. I thought I knew everything about OSPF and ISIS, working last 5 years in services provider industry. But I was wrong after I read through this book. The book gives a fantastic intro into Link State routing then presents OSPF and ISIS individually emphasizing on the similarities and differences from every aspect including adjacency formation, route calculation, failure recovery mechanisms, and packet types. Also gives a primer into the various applications and extended capabilities to support MPLS TE, IPv6 etc This book is now on my shelf as the first book to refer to get answers on OSPF and ISIS for any project work that comes my way as a network consultant. Thank you Jeff for another great peace of work!

I am one of the few who have worked in ISIS and not OSPF..There are very few books on ISIS and this is one of the best there isThree books to be read by anyone interested in IGP1. Routing TCP/IP2. OSPF and ISIS4. The complete ISIS routing protocol5 star anyday

I thought I was buying a great technical discussion on OSPF versus ISIS. Little did I know I would also get a very good history lesson on the early days before OSPF was the de facto enterprise routing protocol. Great all-around book. If you are into digital archaeology and technical reading you will love it!
