Objective
Utilize a systematic approach to troubleshooting a simple network problem.
Scenario
You have been asked to find out why the SanJose1 and Eastasman routers are
advertising their subnets to the ISP router. Your ISP is using EIGRP to connect
to the SanJose1/Eastasman routers. Your company does not want each subnet
reported to the ISP, only the overall subnet number that you are using
(192.168.1.0/24). The ISP has given you the user level password (cisco) for the
ISP router so you can monitor the results of your troubleshooting.
Lab Tasks
Build the network according to the diagram above and load the appropriate
‘broken’ configuration files to each router. Save the configurations and reload
each router.
