By the end of this module, learners will have a solid grasp of WAN fundamentals, enabling them to comprehend more advanced networking concepts and configurations.
Configuring WAN Links: In this module, participants will learn about two key WAN protocols: High-Level Data Link Control (HDLC) and Point-to-Point Protocol (PPP). The module will begin with an explanation of the characteristics, advantages, and use cases of both HDLC and PPP in WAN environments. Learners will then move on to hands-on configuration, where they will set up HDLC and PPP connections on routers
Routing: This module introduces the essentials of routing, explaining how a router learns and manages routes through both static configurations and dynamic protocols. Participants will explore the components of a routing table, including route types and metrics, and understand how these elements determine the optimal path for packet delivery. The module also covers the interaction between Layer 2 forwarding and Layer 3 routing, illustrating how these layers work together to efficiently deliver packets to their destinations.
Static Routes: In this module, participants will learn how to configure static routes on a router, focusing on three key types: default routes, host routes, and floating routes. The module provides step-by-step guidance on setting up each route type, explaining their purposes and how they influence traffic flow within a network. Participants will also gain hands-on experience configuring these routes in various scenarios, ensuring they can effectively manage network traffic and implement backup routes for redundancy.
Dynamic Routing Protocols: This module covers the various types of dynamic routing protocols, including Distance Vector, Link State, and Hybrid protocols, explaining their functions, advantages, and disadvantages. Participants will explore how these protocols automatically manage and distribute routing information within a network. The module then focuses on configuring the Routing Information Protocol (RIP) on a network, providing practical steps to implement RIP, and discussing its use cases, benefits, and limitations in dynamic routing environments.
OSPF: This module provides the basics of the Open Shortest Path First (OSPF) protocol, explaining how it operates as a Link State routing protocol to efficiently manage and distribute routing information within a network. Participants will learn about OSPF’s key features, such as link-state advertisements (LSAs) and the Dijkstra algorithm. The module includes hands-on exercises for configuring OSPF on a network.
OSPF Settings: In this module, participants will dive into advanced OSPF settings, focusing on the role of hello timers, costs, and load balancing in optimizing network performance. The module explains how OSPF hello timers impact neighbor relationships, how OSPF cost influences route selection, and how load balancing can be achieved across multiple paths. Learners will also gain practical experience configuring these OSPF settings on a network, ensuring they can fine-tune OSPF operations to meet specific network requirements.
OSPF Multi-Access Networks: This module addresses the unique challenges OSPF faces in multi-access networks, such as broadcast domains where multiple routers can form adjacencies. Participants will learn about potential issues like excessive LSA traffic and how OSPF uses the Designated Router (DR), Backup Designated Router (BDR), and DROTHER roles to manage these environments efficiently.
