Troubleshooting Lab Challenge 1

April 19th, 2015 in Lab Challenges Go to comments

Note: We created this lab challenge to help you get some practice with networking problems only. These labs are only for fun and do not appear in the TSHOOT exam. Please let us know if you like this simulator or not so that we can continue making other simulators in the future. Any suggestion, recommendation, error reports are warmly welcomed!

Troubleshooting Lab Challenge 1:

A network engineer has edited their network configuration and now your customer is experiencing network issues. Some reports said that users connected to CLIENT router (R4) cannot reach the services located at SERVER router (R3). They have contacted you to resolve the issues and return the network to full functionality.


To troubleshooting effectively you should understand how this network works. We summarize it as follows:

+ OSPF is running among R1, R2, SW5 and SW6, all are in Area 0
+ R1 and R2 are two DHCP Servers
+ R1 is only responsible for answering DHCP Request from SERVER (R3)
+ R2 is only responsible for answering DHCP Request from CLIENT (R4)
+ Interfaces E0/0 of SERVER and CLIENT is running DHCP to request IP addresses
+ There is an access-list named “edge_security” on SW5 that prevents devices with source IP of 172.16.0.x from accessing the SERVER.

There are 9 tickets waiting for you to resolve. Below are the links to access them:

Ticket 1 Ticket 2 Ticket 3 Ticket 4 Ticket 5
Ticket 6 Ticket 7 Ticket 8 Ticket 9  

Please try your best to solve these tickets!

You can find the solution and explanation for each ticket here.

    I need to re-certified for my CCNP routing and switching and all I need is to pass one of the same test. what material would you recommend? I am planning signing up on the premium membership and purchase the VCE from examcollection for this test. I remember I used this site last 3 years ago and the labsim was very close to the ones on the test. Not sure if the test has changed at all. I work with routers and switches. I have a week to prepare
    Please advise

    Does anyone know where I can find any Zip files that will have the CCNP T-Shoot topology for GNS3 or Packet Tracer so one can get hands on troubleshooting, instead of reading and trying to determine the issue? Like what is given when you take the T-Shoot test.

    Meaning a pre-configured topology for GNS3 or Packet Tracer that has something configured incorrect and one must sign on and troubleshoot and make changes to get topology to work.

    “Please let us know if you like this simulator or not so that we can continue making other simulators in the future.”

    Yes I like so much this Troubleshooting Lab. Please I ask you to continue making other simulators in the future. They are very helpful. I learned a lot by doing them.

    “Any suggestion, recommendation, error reports are warmly welcomed!”

    Error report:

    Ticket 4 has this problem:

    SW5#show ip int vlan 200
    Vlan 200 is up, line protocol is up
    Internet address is
    Broadcast address is
    Address determined by the setup command
    MTU is 1500 bytes
    Helper address is ——————> HERE IS THE ERROR

    The output must be:

    “Helper address is not set”

    In this manner this match with this output:

    SW5#show run
    interface Vlan200
    ip address
    ip access-group edge_security out
    !———————————————————> There is no ip helper address.

    And for that reason the solution is:

    Under interface Vlan 200, enter ‘ip helper-address’ command.

    Hope this help.

    Thanks a lot again networktut team, best regards.
