Routing is simultaneously the most complicated function of a network and the most important. Most
knowledgeable people agree that networking and routing technologies have been around about 25 years.
The concept of routing actually dates back to the late 1950s, when computing was still an arcane science
in its infancy. Precious few organizations had a single computer, much less multiple computers that
needed to be linked together. Internetworking, the interconnection of multiple computers, was still more
of a futuristic vision than a reality.
IP best-effort packet-delivery service:
IP addressing and packet forwarding with datagram mode.
Multiplexing accomplished by transport protocols (TCP, UDP).
And how to build on top of the narrow waist:
Domain Name System (DNS) for resolution between name and
Dynamic host configuration protocol-DHCP for IP

The following will be discussed in this chapter: Routing overview, static and dynamic route comparison, static route configuration, default route forwarding configuration, static route configuration verification, dynamic routing protocol overview, features of dynamic routing protocols, the IP classless command.
This book describes the TCP/IP protocol suite, but from a different perspective than other
texts on TCP/IP. Instead of just describing the protocols and what they do, we'll use a
popular diagnostic tool to watch the protocols in action. Seeing how the protocols operate in
varying circumstances provides a greater understanding of how they work and why certain
design decisions were made. It also provides a look into the implementation of the protocols,
without having to wade through thousands of lines of source code....
Administering Cisco QoS in IP Networks discusses IP Quality of Service (QoS) and
how it applies to Enterprise and Service Provider environments. It reviews routing
protocols and quality of service mechanisms available today on Cisco network
devices (routers, switches, etc.).This guide provides examples and exercises for a
hands-on experience to give you the background and necessary details to implement
these capabilities in your network today.
As the Internet continues to grow exponentially, the need for network engineers to build, maintain,
and troubleshoot the growing number of component networks also has increased significantly.
Because network troubleshooting is a practical skill that requires on-the-job experience, it has
become critical that the learning curve necessary to gain expertise in internetworking technologies be
reduced to quickly fill the void of skilled network engineers needed to support the fast-growing
Choosing an IP routing protocol is an important step. The right protocol can make your routing
operate efficiently, and the wrong one can make your life difficult. Each protocol has its own
pros and cons, and works better in some situations than others. In this paper, we explore the
strengths and weakness of RIP, EIGRP, OSPF, and IS-IS, and discuss when it is appropriate to
use each. We will evaluate each protocol in terms of five criteria:
• Convergence speed
• Ease of use
• Network topology required
• Vendor support
• IPv6 support...
Every IP address must be accompanied by a subnet mask. By now you should be able to look
at an IP address and tell what class it is. Unfortunately your computer doesn’t think that way.
For your computer to determine the network and subnet portion of an IP address it must
“AND” the IP address with the subnet mask.When you take a single network such as 126.96.36.199 and divide it into five smaller networks
(188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168, 22.214.171.124) the outside
world still sees the network as 192.100.10.
