Objective
Utilize a systematic approach to troubleshooting an IPX network.
Scenario
As the Enterprise Network Administrator, you are responsible for maintaining
connectivity between remote offices at your company. SanJose1 router is lo-
cated at the corporate office and the Singapore router is located at one of the
many branch offices. In the WAN, you’re using IPX EIGRP and you’re running
IPX RIP on the LAN segments.
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. Clock rates have been applied to all serial interfaces.

Confirm connectivity by performing ipx pings between the routers. All pings
should be successful. The three workstations in the diagram should have only
IPX with NetBIOS support installed. If necessary, on the three workstations, in-

stall the IPX/SPX compatible protocol with NetBIOS support. Also, through the
network properties enable file sharing on these workstations. Create a shared
folder on each of these workstations.
Scenario
You have been asked to resolve a connection issue between hosts on network
ABC1 and hosts on network ABC3. The users complain that they are unable to
view a necessary shared folder on Host B via network neighborhood. Hosts A
and C are able connect to each other. After reviewing the settings of Host B
you determine it’s not a workstation issue.
Step 1
Define the problem you are experiencing.





Step 2
Gather relevant facts about the situation at hand. Upon examining the router,
what factual information can you obtain from the router?
Some useful troubleshooting commands are:
show ipx route
show ipx interface
show ipx eigrp neighbors
show ipx eigrp topology
debug ipx routing activity

debug ipx eigrp events
debug ipx eigrp neighbor





Step 3
Examine the facts you have just listed. Based on your observations, list some
potential causes of the problem.

Step 4
Formulate an action plan to solve this problem.





Step 5
Implement your action plan and attempt to fix the problem. Log all your
changes.

Step 6
What were the results of your implementation? Did it fix the problem? List your
results and observations below. Are the shared folders available throughout the
network?





Step 7
If your solution did not fix the problem, repeat the process. If your solution did
fix the problem, document your fix below.
