Cisco OSPF Command and Configuration Handbook

CiscoPress's "OSPF Command and Configuration Handbook" by Dr. Parkhurst is simply a great book. Don't get me wrong, you are not going to walk away from this book understand the underlying root-theory of OSPF. You will need a basic understanding of OSPF to properly benefit from this book - it's not OSPF-101. Nor will you find a whole and complete, complex OSPF config. What you will find is nearly every major OSPF command at the time of the book's printing. This book is both a compliment to any Network Administrator or a candidate for the CCIE R&S lab. The book does an excellent job at breaking down the major categories of OSPF commands (neighbor commands, network commands, the difference types of default route generation, etc...). The book also does a superb job at showing the dangers and pitfalls of OSPF demand-circuit (certainly a likely area to study for the CCIE lab). What I particularly enjoy is each command is broken down both by command structure and then used in a configuration (the config is amended to only show the command and other relevant commands). This way you have a fuller appreciation of the command being used in context. Some typos that I notice:Page 193 - what is documented as Loopback 0 should be Loopback 1.Page 321 - the book incorrectly discusses the use of the subnet command. The book asserts that if the subnet command is not used, that non-classful subnets will be redistributed. This is simply not true and is, indeed the reason for the subnet command - to redistribute non-classful subnets. Page 415 - frame-relay map statements must be made for the other DLCIs to establish an OSPF neighbor relationship.Overall, I love the concept of this book. I wish CiscoPress would come out with more books like this. They provide a value in that they discuss commands in ways not found in other CiscoPress books or the Cisco website. I give this book 5 pings out of 5: !!!!!
