The course also describes how NAT provides the ability to convert one address to another. One of the biggest challenges in networking is addressing, and the challenge only becomes bigger as networks scale and grow connected. NAT offers great flexibility in the use of addresses. Topics include Remote Access Connectivity, Remote Access Authentication and Hashing, Configuring PPP for CHAP Authentication, PPP Callback and Compression, Multilink PPP and Login Banners, Link Quality Monitoring and Troubleshooting PPP, NAT Considerations and Terminology, NAT in Operation, Configuring Load Sharing, and NAT Troubleshooting.

Lesson 3: Modems and Asynchronous Connections (1.0) hour

Modems and Asynchronous Connections teaches you how to configure an asynchronous line, select the proper cables and adapters, set up modem autoconfiguration, configure modems manually, maintain the modemcap database, and debug modem autoconfiguration. This course describes how to correctly choose and deploy the proper cabling and master the configuration of the router, its resources, and modems attached to the router. Asynchronous connections via modem are an integral part of any wide-area network (WAN) implementation. Although it has been relegated to backup status in most cases, the asynchronous connection still has many advantages, including its ready availability and low cost. Topics include Modem technologies and standards, Configuring the router, Attaching and using the modem, Configuring the modem, and Troubleshooting the modem.

Lesson 4: Using ISDN Connections (1.0) hour

Using ISDN Connections teaches you how to understand the relationship of ISDN components, describe call setup and teardown, configure an ISDN interface, and troubleshoot an ISDN configuration. This course covers the two forms of Integrated Services Digital Network (ISDN): Basic Rate Interface (BRI) and Primary Rate Interface (PRI). ISDN usage, equipment and call progress, are discussed prior to a detailed description of BRI and PRI configuration. Topics include ISDN Connections, Equipment Used with ISDN, Call Progress Setup and Teardown, ISDN BRI Configuration and Routing, ISDN BRI Bandwidth Usage and Additional Options, ISDN PRI Controller and Timeslots Configuration, ISDN PRI Layer 1 Communication & Interface Configuration, and ISDN Troubleshooting and Debugging.

Lesson 5: Using Frame Relay Connections (1.0) hour

Using Frame Relay Connections teaches you how to determine correct line speeds, configure interfaces for Frame Relay, monitor Frame Relay operation, and troubleshoot Frame Relay operation. This course covers the concepts, components, and use of Frame Relay. Frame Relay is a standard supported by both the American National Standards Institute (ANSI) and the International Telecommunication Union that defines the encapsulation from the customer premises equipment (CPE) to the data circuit-terminating equipment (DCE) at the regional provider's switch. Frame Relay configuration, traffic shaping, fragmentation, and troubleshooting are presented. Topics include Frame Relay Concepts, Frame Relay Components, Connecting a Single Interface to Multiple Locations, Traffic Shaping Configuration and Commands, Frame Relay Fragmentation, PIPQ, and EIGRP, and Monitoring and Troubleshooting Frame Replay Operation.

Lesson 6: Dial-on-Demand and Broadband (2.0) hours

Dial-on-Demand and Broadband teaches you how to understand DDR (dial-on-demand routing), articulate dialer profiles and interface, describe broadband, cable modems, and DSL, describe a cable modem infrastructure, identify different DSL types, describe ADSL, PPPoE and PPPoA, configure PPPoE and PPPoA, and troubleshoot DSL configurations. This course covers the DDR process by which a link is created on demand. As traffic needs to cross the WAN, a circuit is completed from the source router to the destination, allowing the traffic to cross. DDR circuits are useful when you pay for access based on the amount of time the circuit remains up. The second part of this course examines broadband technologies. A cursory look at direct broadcast satellite (DBS) and fixed wireless providers is followed by more on cable modems. Four wireless segments: local multipoint distribution service (LMDS); multichannel multipoint distribution service (MMDS); industrial, scientific, and medical (ISM); and unlicensed national information infrastructure (U-NII) bands are also presented. Topics include Interesting Traffic, Dialer Profiles, Incoming Call with Rotary Groups, Configuration Example and Explanation, Cable Broadband, DSL and ADSL Operation, Configuring PPPoE and PPPoA, and Troubleshooting DSL.

Lesson 7: Enabling Backup Connections and Management of Traffic (2.0) hours

Enabling Backup Connections and Management of Traffic teaches you how to use the backup load command, determine routing protocol preferences, calculate backup delay, describe basic queuing, compare advanced queuing techniques, articulate traffic importance, and describe compression types. This course covers the use of dial backup to back up a permanent connection. Having a second connection that can move data in the event the primary connection fails is a wise move for today's corporate environment. This course also covers the use of each of the three types of queuing (WFQ, PQ, and CQ), how to configure the router for each type, and the potential pitfalls of each. The Link, Payload, Header, and Modem data compression types are presented. Topics include Dial Backup, Using Dial Backup with Dialer Profile, Understanding Basic Queuing, WFQ Queuing Concepts and Configuration, PQ Queuing Concepts and Configuration, CQ Queuing Concepts and Configuration, Advanced Queuing Concepts, and Data Compression.
