Chapter 10

Routing Protocols

The Following CompTIA Network+ Exam Objectives Are Covered in This Chapter:

• 1.4 Explain the purpose and properties of routing and switching.
  • EIGRP
  • OSPF
  • RIP
  • Routing metrics
• Hop counts
• MTU, bandwidth
• Costs
• Latency
• Next hop
• Routing tables
• Convergence (steady state)
• 2.1 Given a scenario, install and configure routers and switches.
  • Routing tables

Routing protocols are critical to a network’s design. This chapter focuses on dynamic routing protocols. Dynamic routing protocols run only on routers that use them in order to discover networks and update their routing tables. Using dynamic routing is easier on you, the system administrator, than using the labor-intensive, manually achieved, static routing method, but it’ll cost you in terms of router CPU processes and bandwidth on the network links.
