Summary
T
his chapter covered IP routing in detail. It is important that you under-
stand the basics covered in this chapter, because everything that is done on a
Cisco router must have some type of IP routing configured and running.
This chapter covered the following topics:
IP routing and how frames are used to transport packets between rout-
ers and to the destination host
Static routing and how an administrator can use it in a Cisco inter-
network
Default routing and how default routing can be used in stub networks
Dynamic routing and how to solve loops in distance-vector routing
protocols
Configuring and verifying RIP routing
Configuring and verifying IGRP routing
