O'Reilly Author Offers a Straightforward Approach to IP Routing
Sebastopol, CA--The routing of IP packets takes place behind the
scenes, so that the typical network user who sends an email or views a
web page may never give more than a passing thought as to how the
information moves from one place to another. In his just-released book,
(O'Reilly, US $34.95), author Ravi Malhotra offers the
analogy of a traveler boarding a train in one location and traveling
via a route comprising several stops to a distant location, where she
emerges, bags in hand. In the same way, IP packets in an IP network are
moved from router to router to their final destination. While IP
routing is a vast and intricate subject, especially in the context of
the global IP network, it is an essential subject for network
administrators to understand in order to configure routers and routing
protocol for optimum use and efficiency.
This latest addition to O'Reilly's acclaimed series of books for
network administrators introduces IP routing as it is implemented using
Cisco routers. Each section of IP Routing leads the reader through
the basics of configuring routing protocols, beginning with the
simplest, Routing Information Protocol (RIP). Malhotra moves on to more
complex routing protocols in subsequent chapters, including the
Interior Gateway Routing Protocol (IGRP), the Enhanced Interior Gateway
Routing Protocol (EIGRP), Routing Information Protocol Version 2
(RIP-2), and Open Shortest Path First (OSPF).
Among the questions Malhotra addresses are: What is the
packet-forwarding process? How is the routing table maintained? How do
Distance Vector algorithms work? How do classful and classless route
lookups differ? These and other concepts are illustrated in Malhotra's
discussions of traditional routing protocols.
Finally, Malhotra provides a detailed presentation of Border Gateway
Protocol 4 (BGP-4). Says Malhotra, "BGP is the glue that binds the
thousands of networks that combine to make up the Internet. Routing in
the Internet is quite different from routing in intranets. I have
included several new concepts in this chapter."
For network and system administrators, IP Routing is a
straightforward, jargon-free introduction to the basics of IP routing.
Readers will master not only the fundamentals of all major routing
protocols, but also the principles on which the protocols are based.
Intended for anyone with an interest in the subject, IP Routing is
appropriate for beginners as well as for those already familiar with IP
routing who seek a better understanding of the underlying concepts.
