OSPF Anatomy of an Internet Routing Protocol
Written for TCP/IP network administrators, protocol designers, and network application developers, this book gives the most complete and practical view ever into the inner workings of Internet routing. The book focuses on OSPF (Open Shortest Path First), a common TCP/IP routing protocol that provides robust and efficient routing support in the most demanding Internet environments. A methodical and detailed description of the protocol is offered and OSPF's role within the wider context of a TCP/IP network is demonstrated.
Practical throughout, the book provides not only a theoretical description of Internet routing, but also a real-world look into how theory translates into practice. It shows how algorithms are implemented, and how the routing protocols function in a working network where transmission lines and routers routinely break down.
You will find clear explanations of such routing fundamentals as how a router forwards packets, IP addressing, CIDR (Classless Inter-Domain Routing), the routing table, Internet routing architecture, and the two main routing technologies: Distance Vector and link-state algorithms. OSPF is discussed in depth, with an examination of the rationale behind OSPF's design decisions and how it has evolved to keep pace with the rapidly changing Internet environment. OSPF topics covered by the book include the following: OSPF areas and virtual links NBMA (Nonbroadcast multi-access) and Point-to-MultiPoint network segments OSPF configuration and management Interaction with other routing protocols OSPF cryptographic authentication OSPF protocol extensions, including the Demand Circuit extensions and the multicast extensions to OSPF (MOSPF) An OSPF FAQ
IP multicast and multicast routing are also discussed. Methods for debugging routing problems are explained, including a catalog of available debugging tools. The book also offers side-by-side comparisons of all the unicast and multicast routing protocols currently in use in the Internet.
You will come away from this book with a sophisticated understanding of Internet routing and of the OSPF protocol in particular. Moreover, the book's practical focus will enable you to put this deeper understanding to work in your network environment.
Ospf Network Design Solutions
The comprehensive reference for OSPF network design and deployment
- Understand the full dynamics of OSPF network components, how they interact with one another, and how to configure them
- Increase the efficiency of your OSPF network through a variety of performance tuning techniques
- Apply load balancing to enhance OSPF's capability to adapt to network topology changes
- Ensure seamless communication between OSPF and other Interior Gateway Protocols (IGPs) and OSPF and BGP through redistribution
- Optimize network stability and efficiency with OSPF summarization
- Maximize your ability to properly manage an ever-changing OSPF network landscape through Simple Network Management Protocol (SNMP) and Management Information Bases (MIBs)
- Develop a practiced, tested security plan to protect your OSPF network
- Optimize the efficiency and bandwidth of your OSPF network through the integration of MPLS
- Complete your basic OSPF knowledge gaps with a boiled down summary of the OSPF RFCs
One of the most prevalent Interior Gateway Protocols (IGPs), OSPF is in use in numerous networks across the globe. Open Shortest Path First (OSPF) is also one of the most widely tested protocols if you choose to pursue a networking certification. From a technical perspective, the overwhelming presence of OSPF ensures that you will encounter it at some point in your career. As a result, every networking professional should understand how OSPF operates, how to configure and troubleshoot this important protocol, and most importantly how to design a network that uses OSPF.
CBT Nuggets Cisco CCVP
This training provides the core knowledge of Voice over IP (VoIP) required for implementing and supporting data and voice integration solutions at the network level. It helps you grasp the VoIP vision, and to answer three major questions most companies have about VoIP solutions:
- Why are so many companies moving to VoIP?
- What are the benefits of using VoIP?
- Is VoIP right for our company?
Once the CVOICE videos help you answer these three questions, they get into the nitty-gritty of VoIP implementation. They teach you how to move an existing PBX or Key System based network to the newer VoIP technology without getting rid of all your old equipment, so you can maximize the cost efficiency of your VoIP implementation. They teach you how to deploy a worldwide VoIP infrastructure, even using lower-end equipment. The videos also cover techniques that allow you to configure your Cisco router to continually monitor the WAN line quality and dynamically change connections as necessary.
"CVOICE [Exam-Pack: 642-432 from CBT Nuggets] not only prepares you for the Cisco exam, but also has multiple practical VoIP deployment videos showing exactly how an administrator would set this up in the real world," explained instructor Jeremy Cioara.
The videos cover all objectives for the Cisco CVOICE exam 642-432, which is required for CCVP, Cisco IP Telephony Express Specialist and Cisco IP Telephony Support Specialist certifications. A thorough understanding of Cisco networking such as CCNA or equivalent knowledge is recommended before viewing these videos. The training contains 19 videos providing more than 11 hours of instruction.

- Utilize Layer 3 QoS to classify varying levels of service with the Catalyst 6500 MSFC and Flexwan
- Understand how to apply QoS in campus network designs by examining end-to-end case studies
Quality of service (QoS) is the set of techniques designed to manage network resources. QoS refers to the capability of a network to provide better service to selected network traffic over various LAN and WAN technologies. The primary goal of QoS is to provide flow priority, including dedicated bandwidth, controlled jitter and latency (required by some interactive and delay-sensitive traffic), and improved loss characteristics.
While QoS has become an essential technology for those organizations rolling out a new generation of network applications such as real-time voice communications and high-quality video delivery, most of the literature available on this foundation technology for current and future business applications focuses on IP QoS. Equally important is the application of QoS in the campus LAN environment, which is primarily responsible for delivering traffic to the desktop.
