"The" definitive tcpip/IGP reference book,
This review is from: Routing TCP/IP: v. 1: Authorized CCIE Preparation (CCIE Professional Development) (Hardcover)
Jeff Doyle has a sense of humour. In a book this thick, containing this much technical information, that in itself is reason to buy this book. He can make a dry topic sound interesting, and has the (scarce) ability to make technically challenging subjects relatively easy for the reader to comprehend (his analogies are excellent). I have had this book for 3yrs now, and still refer to it on average at least once a week. Buy this book (and part2) along with Kennedy Clarks Switching book, and the CCIE is a stones throw away.
