LAN Switch
LAN switches are used to interconnect multiple LAN segments. LAN switching provides dedicated, collision-free communication between network devices, with support for multiple simultaneous conversations. LAN switches are designed to switch data frames at high speeds. Figure 5-4 illustrates a simple network in which a LAN switch interconnects a 10-Mbps and a 100-Mbps Ethernet LAN.

Chapter 6. Routing Basics
Objectives
Learn the basics of routing protocols.
Learn the differences between link-state and distance vector routing protocols.
Learn about the metrics used by routing protocols to determine path selection.
Learn the basics of how data travels from end stations through intermediate stations and on to the destination end station.
Understand the difference between routed protocols and routing protocols.
This chapter introduces the underlying concepts widely used in routing protocols. Topics summarized here include routing protocol components and algorithms. In addition, the role of routing protocols is briefly contrasted with the role of routed or network protocols. Subsequent chapters in Part VII, "Routing Protocols," address specific routing protocols in more detail, while the network protocols that use routing protocols are discussed in Part VI, "Network Protocols."
