Task 5: Save the Packet Tracer File
Save your Packet Tracer file as LSG02-0101-end.pka. You will use this file to complete some of the
remaining exercises in this chapter.
Building the Routing Table
The primary function of a router is to forward packets toward the destination network, the destination
IP address of the packet. To do this, a router needs to search the routing information stored in its rout-
ing table. In this section, you will learn how a router builds the routing table. Then, you will learn the
three basic routing principles.

Introducing the Routing Table
A routing table is a data file stored in
RAM
that is used to store route information about directly con-
nected and remote networks.
There are two major types of routes in the routing table:
A
directly connected
network: When a router's interface is configured with an
IP address
and
subnet mask
, the interface becomes a host on that attached network.
