High Availability Commands for CCNP BCMSN: Nov 30, 2007; This chapter provides information on and commands for Hot Standby Routing Protocol, Virtual Router Redundancy Protocol, and Gateway Load Balancing Protocol.

Home Network Router Security Secrets: Apr 7, 2006; Ever delve inside your home network routers and use the hidden security settings that can lock down a network nice and tight? Most people never do. Andy Walker reveals 10 secrets on how to easily access your router's security settings.

CCNA Exam Prep: Data Link Networking Concepts: Feb 3, 2006; This chapter will help you prepare for the CCNA exam, with a focus on data link networking. Sample questions with detailed answers are included to help you review for the exam.

CCNA Exam Cram: Concepts in IP Addressing: Jan 13, 2006; The CCNA exam(s) require a near-perfect fluency in subnetting. Success requires speed and accuracy in answering the many questions you will see on this topic. The key to this level of fluency is practice—you must work at your skills until they become second nature. The following sections discuss binary and hexadecimal numbering systems as compared with the more familiar decimal system.

MPLS Traffic Engineering: Jan 13, 2006; MPLS Traffic Engineering (MPLS TE) is a growing implementation in today's service provider networks. MPLS adoption in service provider networks has increased manifold due to its inherent TE capabilities. This chapter provides you with information on the operation and configuration of MPLS TE on Cisco routers.

CCNA Practice Questions: Basic IOS Configuration and Basic Serial WAN Connectivity: Jan 6, 2006; Test your knowledge and preparedness for the CCNA exam with 50 practice questions and answers from Exam Cram 2.

MPLS Network Design Nuts and Bolts: Jan 6, 2006; Network convergence is upon us as legacy networks across the world are being upgraded to MPLS. However, this relatively new technology requires a broad range of skills, not least of which is design. The same was true in the old days, when separate teams of boffins managed voice, video, and data networks, except that now it's all IP-based! As Stephen Morris shows, it's really not too difficult to get an overview of the skills required to design the latest MPLS networks without reading a gazillion books and RFCs.

CCNP Exam Prep: Traditional Spanning Tree Protocol: By David Hucaby; Dec 22, 2005; This chapter discusses the theory and operation of the STP with an eye toward passing the CCNP BCMSN Exam. More specifically, the original, or traditional, STP is covered, as defined in IEEE 802.1D.

The Basic Uses of TCP/IP Route Maps: Dec 9, 2005; Route maps are similar to access lists; they both have criteria for matching the details of certain packets and an action of permitting or denying those packets. This chapter explains the basics of Route Maps. Included are sample exercises to help you practice administration and use of Route Maps.

Scaling OSPF and IS-IS: Dec 1, 2005; Scalable may well be one of the most overused words in the network designer's lexicon. It applies to protocols, to software, to operating systems, to hardware architecture, and to networks. Scalable means, simply enough, the ability of the relevant entity (select one from the list just given) to get much bigger than it presently is without reducing performance, stability, or accuracy; making your customers angry; or getting you fired. This chapter covers scalability in OSPF and IS-IS.

CCNP Self-Study: Understanding and Configuring Multilayer Switching: Nov 11, 2005; This chapter provides you with details, architecture, and methods of multilayer switching on Catalyst switches. An understanding of multilayer switching is necessary for network designers, administrators, and operators for deployment and troubleshooting purposes.

Analyzing MPLS VPN Security: Oct 6, 2005; VPN users have certain expectations and requirements for their VPN service. In a nutshell, they want their service to be both private and secure. In other words, they want their VPN to be as secure as with dedicated circuits while gaining the scalability benefits of a shared infrastructure. Both concepts, of privacy and security, are not black and white, and need to be defined for a real world implementation. This chapter introduces you to VPN MPLS security requirements.

Which Routing Protocol Should My Network Use?: Sep 30, 2005; One of the toughest questions facing network engineers is which routing protocol to use. Each has its strengths, and each works better with some network designs than with others. This chapter will help you decide which routing protocol is best for your particular network.

Network+ Exam Cram: Networking Devices in Modern Networks: Aug 5, 2005; This chapter covers the various networking devices used in modern networks with an eye toward passing the Network+ Exam. Sample questions with detailed answers are included to help you practice.

Interexchange Carrier MPLS Network Design Study: Jul 22, 2005; USCom is a fictitious nationwide data and long-distance voice service provider in the U.S. This chapter discusses the current USCom MPLS network design, its evolution, and how USCom characteristics and objectives influenced the corresponding design decisions that were made in order to illustrate how design decisions should stem from the characteristics of your company.

Troubleshooting Any Transport over MPLS Based VPNs: Jun 10, 2005; MPLS Layer 3 VPNs allow a service provider to provision IP connectivity for multiple customers over a shared IP backbone, while maintaining complete logical separation of customer traffic and routing information. Learn more about MPLS Layer 3 VPNs in this sample chapter from Cisco.

CCNA Command Quick Reference: Routing and Routing Protocols: Jun 3, 2005; This chapter condenses the CCNA Routing commands into an easy-to-use chart for quick reference.

Layer 2 VPN Architectures: Understanding Any Transport over MPLS: May 12, 2005; This chapter provides an overview of LDP, including LDP components and operations that are related to pseudowire emulation over MPLS along with an explanation of the control signaling and data switching details of AToM.

Understanding High Availability of IP and MPLS Networks: Jan 14, 2005; This chapter describes major sources of network failures and provides an overview of techniques that are commonly used to improve availability of IP/MPLS networks. In particular, this chapter outlines mechanisms for reducing network downtime due to control-plane failures.
