Module 7 Summary
Before students begin Module 8, they must be able to configure and troubleshoot RIP and
IGRP by themselves.
Online assessment options include the end-of-module online quiz in the curriculum and the
online Module 7 exam. Formative skill assessments such as timed competitions to see who
can get hands-on or e-Lab routing to work the fastest should be used. The emphasis of any
assessment should be on the ability to demonstrate mastery.
Students should understand the following main points:
• How routing information is maintained through distance vector protocols
• How routing loops occur in distance vector
• How to define a maximum to prevent count to infinity
• How to eliminate routing loops through split horizon
• Route poisoning
• How to avoid routing loops with triggered updates
• How to prevent routing loops with holddown timers
• How to prevent routing updates through an interface
• Load balancing across multiple paths
• RIP process
• RIP configuration
• The ip classless command
• Common RIP configuration issues
• Load balancing with RIP
• How to integrate static routes with RIP
• How to verify RIP configuration
• IGRP features
• IGRP metrics
• IGRP routes
• IGRP stability features
• How to configure IGRP
