This book introduces you to the basic concepts of IP networking, the IP Suite, and the basics of routing; IP routing protocols; Ethernet technology and Ethernet switched networks. This book is composed of four parts.  The first part of this book, Ethernet Fundamentals, introduces you to Ethernet technology and is designed to provide you with a comprehensive high level understanding of various aspects of Ethernet. Upon completion of this part, you will gain a solid understanding of the operational and theoretical components of an Ethernet network.  The second part, Ethernet Switching Resiliency, provides a basis for understanding Ethernet switched networks. It is designed to provide you with a comprehensive understanding of various aspects of Ethernet. Upon completion of this part, you will gain a solid understanding of the operational and theoretical components of an Ethernet Switched network and the standards that make them work.  The third part, Internet Protocol (IP) Fundamentals, provides an introduction to the basic concepts of IP networking, the IP Suite, and the basics of routing. Upon completion of this part, you will gain a solid understanding of how a packet moves from the source workstation to the destination workstation and the major steps along the way, including how data is segmented, how headers are added or stripped off, and how a file travels through the IP stack.  The fourth part, IP Routing, provides a fundamental understanding of IP routing protocols with emphasis on the Open Shortest Path First (OSPF) protocol. This part explains the theory, configuration, operation, and support of the OSPF protocol with special consideration given to OSPF areas, summary ranges, and external routes. The part also includes a discussion of address masks, Routing Information Protocol, the use and configuration of IP route policy filters along with an introduction to Border Gateway Protocol (BGP) and IPv6. This part provides you with the necessary skills to configure and manage OSPF, RIP, BGP, and route policy filters on the Nortel Ethernet Routing Switch.  This book will help prepare you for the Nortel Certified Technology Specialist (NCTS) certification exam, Nortel Data Networking Technology (920-805).  Key Topics:  - IEEE 802.3 Standard Bandwidth on an Ethernet Network Collision Domains and Broadcast Domains - Virtual LANs (VLANs) and Spanning Tree Algorithm - Ethernet Switches - The Internet and IP Networking - OSI Model and IP Suite Protocol Stack Network Addressing Routing Services, Network Routing, and Routing Tables - Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) - Telnet, File Transfer Protocol (FTP), Simple Mail Transfer Protocol (SMTP), HyperText Transfer Protocol (HTTP) and Domain Name Service (DNS) - IP Routing - Configuring Networks
