| Summary

| An understanding of the following key points should have been achieved: How routing information is maintained through distance vector protocols How routing loops occur in distance vector Defining a maximum to prevent count to infinity Eliminating routing loops through split horizon Route poisoning Avoiding routing loops with triggered updates Preventing routing loops with holddown timers Preventing routing updates through an interface Load balancing across multiple paths RIP process Configuring RIP Using the ip classless command Common RIP configuration issues Load balancing with RIP Integrating static routes with RIP Verifying RIP configuration IGRP features IGRP metrics IGRP routes IGRP stability features Configuring IGRP Migrating RIP to IGRP Verifying IGRP configuration Troubleshooting IGRP
