Lab 9-5: EIGRP Troubleshooting (9.6.3)
Upon completion of this lab, you will be able to
Cable a network according to the topology diagram in Figure 9-12
■
Erase the startup configuration and reload a router to the default state
■
Load the routers with supplied scripts
■
Discover where communication is not possible
■
Gather information about the misconfigured portion of the network along with any other errors
■
Analyze information to determine why communication is not possible
■
Propose solutions to network errors
■
Implement solutions to network errors
■
Document the corrected network
■
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.
The network should also have met the following requirements:
EIGRP routing is configured on the BRANCH1 router.
■
EIGRP routing is configured on the BRANCH2 router.
■
EIGRP routing is configured on the HQ router.
■
EIGRP updates must be disabled on the BRANCH1, BRANCH2, and HQ LAN interfaces.
■
All EIGRP routers must use a process ID of 1.
■
Figure 9-12 shows the topology diagram and Table 9-8 provides the interface, IP address, subnet
mask, and default gateway (where applicable) information for all the network devices depicted in
Figure 9-12.
