Advanced Networking Services and Routing Course

Lesson 1 • Ethernet and Switching Concepts

Examines MAC addressing, Ethernet frame structure, and Layer 2 switching behavior. Grounds students in LAN fundamentals before introducing inter-VLAN routing.

Lesson 2 • OSI Model Layer Overview

Covers all seven OSI layers, their roles, and inter-layer communication. Establishes the conceptual framework used throughout the entire course.

Lesson 3 • Network Devices and Topologies

Identifies routers, switches, firewalls, and their placement in common topologies. Sets the physical and logical context for advanced routing design.

Lesson 4 • TCP/IP Protocol Suite Essentials

Maps TCP/IP layers to OSI equivalents and examines core protocols. Provides the practical protocol knowledge required for all routing topics ahead.

Lesson 1 • IPv6 Header Structure

Analyzes the simplified IPv6 fixed header and extension header chain. Understanding header fields is essential for troubleshooting IPv6 routing behavior.

Lesson 2 • IPv6 Address Types and Notation

Introduces unicast, multicast, and anycast address categories with compression rules. Directly extends IPv4 knowledge to prepare students for IPv6 routing protocols.

Lesson 3 • IPv6 Transition Mechanisms

Examines dual-stack, tunneling, and translation strategies for coexistence with IPv4. Prepares students to manage mixed-protocol enterprise environments.

Lesson 1 • Configuring Static Routes

Demonstrates next-hop and exit-interface static route syntax for IPv4 and IPv6. Hands-on configuration skills transfer directly to lab exercises and real deployments.

Lesson 2 • Static Route Troubleshooting

Applies systematic diagnostic commands to identify and resolve static routing failures. Builds the troubleshooting methodology extended in dynamic routing chapters.

Lesson 3 • Routing Table Fundamentals

Explains how routers build and interpret the routing table. This foundational knowledge governs every forwarding decision in subsequent chapters.

Lesson 1 • Single-Area OSPF Configuration

Covers router ID assignment, network statements, and passive interfaces for OSPFv2. Provides the baseline configuration skills extended in multi-area design.

Lesson 2 • OSPFv3 for IPv6

Adapts OSPF concepts to IPv6 using OSPFv3 address families and link-local sourcing. Builds on OSPFv2 knowledge to enable dual-stack routing deployments.

Lesson 3 • OSPF Protocol Fundamentals

Introduces link-state operation, OSPF packet types, and the SPF algorithm. Establishes the conceptual model required before configuring OSPF neighbors.

Lesson 4 • OSPF Optimization and Tuning

Applies cost manipulation, authentication, and timer tuning to optimize OSPF convergence. These techniques are directly applicable to enterprise and service provider deployments.

Lesson 1 • EIGRP Protocol Mechanics

Explains EIGRP's hybrid routing nature, DUAL algorithm, and neighbor table structure. Foundational understanding of DUAL is required before configuring successors.

Lesson 2 • EIGRP Authentication and Troubleshooting

Secures EIGRP neighbor relationships with MD5 and SHA-256 authentication. Troubleshooting skills developed here apply to multi-protocol environments in later chapters.

Lesson 3 • Named-Mode EIGRP Configuration

Configures EIGRP using the modern named-mode hierarchy for IPv4 and IPv6. Named mode simplifies management and supports address-family-based configuration.

Lesson 4 • EIGRP Metric Calculation

Breaks down the composite metric formula using bandwidth, delay, load, and reliability. Metric mastery enables precise traffic engineering in EIGRP environments.

Lesson 1 • iBGP Scalability and Route Reflection

Solves the iBGP full-mesh requirement using route reflectors and confederations. These scalability techniques are mandatory knowledge for service provider environments.

Lesson 2 • Route Maps and BGP Policy

Applies route maps, prefix lists, and community tagging to implement BGP routing policy. Policy tools learned here are reused in redistribution and filtering chapters.

Lesson 3 • BGP Neighbor Configuration

Covers neighbor statements, update-source loopback, and multihop eBGP configuration. Correct neighbor setup is the prerequisite for all BGP policy and attribute work.

Lesson 4 • BGP Operation and Session Types

Introduces BGP as a path-vector protocol and distinguishes eBGP from iBGP sessions. Understanding session types is essential before configuring BGP neighbors.

Lesson 1 • Redistribution Concepts and Risks

Explains seed metrics, administrative distance conflicts, and routing loop risks. Understanding these risks is mandatory before implementing any redistribution design.

Lesson 2 • Filtering and Route Control Tools

Uses distribute lists, prefix lists, and route maps to control route advertisement. Filtering complements redistribution to enforce routing policy boundaries.

Lesson 3 • Mutual Redistribution Between Protocols

Configures two-way redistribution between OSPF and EIGRP with loop prevention. Builds directly on single-protocol knowledge from Chapters 4 and 5.

Lesson 4 • Policy-Based Routing Configuration

Implements PBR using route maps to override destination-based forwarding decisions. PBR enables application-aware path selection independent of the routing table.

Lesson 1 • Bidirectional Forwarding Detection

Deploys BFD to provide sub-second failure detection for OSPF, EIGRP, and BGP. BFD decouples failure detection from protocol hello timers for faster convergence.

Lesson 2 • First-Hop Redundancy Protocols

Compares HSRP, VRRP, and GLBP for default gateway redundancy. FHRP selection and tuning directly impact end-host failover speed and load distribution.

Lesson 3 • Network Convergence Optimization

Tunes protocol timers, SPF scheduling, and incremental SPF to minimize convergence time. Convergence optimization is the capstone skill integrating all routing protocol knowledge.

Lesson 4 • IP SLA for Network Monitoring

Configures IP SLA probes to measure reachability, jitter, and latency continuously. IP SLA data drives automated failover decisions in FHRP and static routing.
