Troubleshooting Lab Challenge 2:

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.


Recently our corporation has just acquired some companies. Our networking engineers are working to merge their networks into ours. An engineer has edited the network configuration and now our users are experiencing network issues. They have contacted you to resolve the issues and return the network to full functionality.

Below are the IPv4 Layer 3 Topology and IPv6 Topology (No switch is used in this challenge so we don’t have a Layer 2 Topology):




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

+ OSPF process 1 is running between R1, R2, R3, R4 and R5
+ RIP version 2 is running between R2 and R6
+ EIGRP AS 10 is running between R3, R7 and R8
+ Redistribution is configured on R2 & R3 to exchange OSPF, RIP and EIGRP information
+ R5 is connected to an Internet Service Provider (ISP) via BGP 65002. R5 is also providing NAT translation between inside networks ( & and outside network ( &
+ R5 is connected to the OSPF backbone area via a OSPF virtual-link. It is a temporary solution for merging them
+ Two access-lists are applied on R5 to increase security for the inside networks
+ Users are allocated prefixes of & They are represented by Client 1 & Client 2
+ R1, R2 and R3 are connected via DMVPN (this is a new topic in the ROUTEv2 exam. If you don’t understand about DMVPN and NHRP, please ignore ticket 14 & 15.)
+ For security reason, the network between R4 & R5 ( is hidden from all other routers via a filter-list on R4.
+ In the IPv6 Topology R1, R3, R4 and R5 are running OSPFv3 AS#10 while R3 and R8 are running RIPng. Redistribution is performed on R3 so that these two IPv6 routing protocols can see each other.
+ Traceroute commands are not supported in this challenge (that would make the challenge too easy)

There are 15 tickets waiting for you to resolve. Each ticket only contains one error. 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 Ticket 10 Ticket 11 Ticket 12 Ticket 13 Ticket 14 Ticket 15  

We hope you can solve all these problems. The difficulty of this challenge is same of the TSHOOT exam (for routers only). Please tell us if you like them or not so that we can continue making more in the future.

Note: This lab challenge is run on IOS v15 so “no auto-summary” is the default value and this command is hidden by default.

    Please suggest

    Lab 2 ticket 4. The issue is far upstream of R4 but you can not ping the E0/1 interface from anything downstream. The solution would not impact the ability to ping E0/1 on R4. Spent a lot of time trying to figure out why I couldn’t ping that interface. I think this is a mistake in the set up of this ticket/lab.

    on the Ticket #12 answer is : redistribute ospf 10 metric 3 include-connected
    Metric 3 , what is that 3 referring to ?

  5. ticket 12
    March 28th, 2017

    it is actually referring to the metric. Metric that RIP can advertise is 16. Metric of 16 means that the route is unreachable, hence redistributing OSPF with metric 15 and keeping in mind that a RIP router adds an interface cost (default is 1) onto the metric of a received route, the neighbor adds 1 which effectively makes a metric of 16 (route is denoted as unreachable)

    Hi “pass today”, would you know the tickets that are not given in the exam

  17. badsanta
    June 12th, 2017


    I have a probem with ticket number 3.
    It is obviously that the network 2019::38:8 on R8 is not propagated through ospf on R1. That means, on R3 there have to be a missing keyword in the section “redistribute ospf 10 metric 3” named “include connected”.
    But actually this command is configured in the sim as it should be.
    Please check this sim, because for me it was very confusing to find a solution for this problem.

    Kind regards

    Hi again,

    Ticket10 is a little bit tricky, do not let confuse you when you check the neighbor/route connection in the eigrp domain.

    Kind regards

    Hey guys, I have a question about obtaining the CCNP certification. I just completed the switch exam because at the end of this month my CCNA R&S was going to expire. Now i also like to mention that between my CCNA and CCNP switch I did pass my Route exam but my question is, is it still valid? It’s going to be three years ago that I passed my route exam and I wanted to know if passing my switch exam renewed that as well? So by taking the Tshoot now will it complete my CCNP or do i have to take route again?

    2012 May – CCNA passs
    2014 October – Route pass
    2017 October – switch
    Now if i get my Tshoot will I have my CCNP cert?

    @ram — from first one of CCNP exams (Route, Switch or Troubleshoot) you have 3 years to complete CCNP R&S .. once you pass this october CCNP Switch your CCNA was automatically extened to 2020 but unfortunately I have to say that your CCNP Route and Switch will expire if TSHOOT will not be completed by October 2017 (depends of the day when you pass CCNP Route)

    Someone has solution for ticket 4 ?

    I think problem is in R4 with the filter-list, either it should be removed or change the first statement from deny to permit.

    Another solution would be in R5 either add a default route ip route pointing to ISP or add the “default-originate always” command in the OSFP process as only with “default-originate” is not enough due to the fact that default-route is not in the routing table…

    This could be extended to BGP protocol which is not generating a default-route from the ISP and the resulting problem would be in the redistribution of BGP into OSPF, but as in R5 there is not any redistribution amongst protocols, I wouldn’t count on this one.

    On Ticket 10 Question 2, I think the answer should categorize to IPv4 Route Redistribution not IPv4 EIGRP Routing.

    guys, i just want to do the tshoot exam.

    can anyone kindly tell me if the tickets have questions that we need to select from A to D?

    or do we need to fix the issue on tickets by configuring the routers?
