Scenario
In this lab, you will begin by loading configuration scripts on each of the routers. These scripts con-
tain errors that will prevent end-to-end communication across the network. You will need to trou-
bleshoot each router to determine the configuration errors, and then use the appropriate commands to
correct the configurations. When you have corrected all the configuration errors, all the hosts on the
network should be able to communicate with each other.
Figure 2-12 shows the topology for this lab, and Table 2-5 shows the IP addressing, subnet, and
default gateway information for the devices in the topology.
