Scenario

Instructor Note: This lab replaces “Lab 1-2: Basic Router Configuration (1.5.2)” and should be used if the stu-
dent needs extensive review of prior skills.

In this lab activity, you will review previously learned skills, including cabling devices, establishing a
console connection, and executing basic IOS command-line interface operation and configuration
commands. You will also learn to save configuration files and capture your configurations to a text
file. The skills presented in this lab are essential to completing the rest of the labs in this course.
However, you can substitute the shorter version, “Lab 1-2: Basic Router Configuration (1.5.2),” if
your instructor determines that you are proficient in the essential skills reviewed in this lab.

Figure 1-12 shows the topology for this lab, and Table 1-6 shows the IP addressing, subnet, and
default gateway information for the devices in the topology.
