Techniques for optimizing large-scale IP routing operation and managing
network growth
- Understand the goals of scalable network design, including tradeoffs
between network scaling, convergence speed, and resiliency
- Learn basic techniques applicable to any network design, including
hierarchy, addressing, summarization, and information hiding
- Examine the deployment and operation of EIGRP, OSPF, and IS-IS
protocols on large-scale networks
- Understand when and how to use a BGP core in a large-scale network and
how to use BGP to connect to external networks
- Apply high availability and fast convergence to achieve 99.999
percent, or "five 9s" network uptime
- Secure routing systems with the latest routing protocol security best
practices
- Understand the various techniques used for carrying routing
information through a VPN
Optimal Routing Design provides the tools and techniques, learned
through years of experience with network design and deployment, to build
a large-scale or scalable IP-routed network. The book takes an
easy-to-read approach that is accessible to novice network designers
while presenting invaluable, hard-to-find insight that appeals to more
advanced-level professionals as well.
Written by experts in the design and deployment of routing protocols,
Optimal Routing Design leverages the authors' extensive experience
with thousands of customer cases and network designs. Boiling down years
of experience into best practices for building scalable networks, this
book presents valuable information on the most common problems network
operators face when seeking to turn best effort IP networks into
networks that can support Public Switched Telephone Network (PSTN)-type
availability and reliability.
Beginning with an overview of design fundamentals, the authors discuss
the tradeoffs between various competing points of network design, the
concepts of hierarchical network design, redistribution, and addressing
and summarization. This first part provides specific techniques, usable
in all routing protocols, to work around real-world problems. The next
part of the book details specific information on deploying each interior
gateway protocol (IGP)--including EIGRP, OSPF, and IS-IS--in real-world
network environments. Part III covers advanced topics in network design,
including border gateway protocol (BGP), high-availability, routing
protocol security, and virtual private networks (VPN). Appendixes cover
the fundamentals of each routing protocol discussed in the book; include
a checklist of questions and design goals that provides network
engineers with a useful tool when evaluating a network design; and
compare routing protocols strengths and weaknesses to help you decide
when to choose one protocol over another or when to switch between
protocols.
"The complexity associated with overlaying voice and video onto an IP
network involves thinking through latency, jitter, availability, and
recovery issues. This text offers keen insights into the fundamentals of
network architecture for these converged environments."
