Alcatel-Lucent Scalable IP Networks Self-Study Guide

Preparing for the Network Routing Specialist I (Nrs 1) Certification Exam

• Broschiertes Buch

Produktbeschreibung

Includes CD-ROM with test engine and lab exercises
This book is your official self-study guide for the Alcatel-Lucent NRS I Certification. The certification is designed to affirm a solid foundation of knowledge in IP Service Routing, spanning the fundamentals of Layer 2 network technologies, IP addressing and routing, TCP/IP, and Carrier Ethernet services. This book gives you the introductory knowledge required to work successfully in an IP/MPLS and Carrier Ethernet environment that delivers consumer and business services.
After reading this book, you will be able to:
Describe the purpose and operation of common Layer 2 technologies
Describe the IP forwarding process
Develop an IP address plan using IP subnetting and address summarization
Explain the characteristics of dynamic routing protocols and configure basic IP routing using OSPF and BGP
Explain the operation of the Transmission Control Protocol (TCP)
Describe MPLS and how it is used to provide Layer 2 and Layer 3 VPN services across a common provider core
"A practical and thorough guide to the fundamentals of IP Service Routing, the Alcatel-Lucent NRS I Certification has proven to be an invaluable tool for our Operations team. It is a key component of our IP knowledge curriculum. We are encouraging our employees to obtain this certification from Alcatel-Lucent."
--Glenn Garbelman, Director, Video Operations Center (IP Operations) AT&T By offering the new Service Routing Certification Program, Alcatel-Lucent is extending their reach and knowledge to networking professionals with a comprehensive demonstration of how to build smart, scalable networks. Serving as a "course in a book" from Alcatel-Lucent--the world leader in designing and developing scalable systems--this resource pinpoints the pitfalls to avoid when building scalable networks, examines the most successful techniques available for engineers who are building and operating IP networks, and provides overviews of the Internet, IP routing and the IP layer, and the practice of opening the shortest path first.
