EIGRP GRE Troubleshooting Sim

March 19th, 2018 Go to comments

Refer to the topology below. Your company asks you to identify the issues in Phase 1 EIGRP implementation. You have console access on R1, R2, R3 Branch1 and Branch2 routers. Only use show commands to troubleshoot the issues.


Question 1


R1 routing table does not have any EIGRP learned routes so R1 or the link between R1 & R2 is the most likely problem. We should check if the IP addresses on R1 and R2 are correct or not with the “show ip interface brief” command.


Note: You should check the IP address of R2 E0/0 interface (the interface connected to R1) as well.

Question 2


The “main office” here refers to R2 (and other routers behind it). Check Branch2 with the “show ip route” command:


We can see Branch2 only uses (Branch 1 – the secondary path) to reach R2 and the subnets behind. Branch2 does not use the primary path (directly connected to R2) so there must be a problem with the connection between R2 and Branch2. Check Branch2 router with the “show running-config” command and we can see an access-list is blocking EIGRP packets advertised to Branch2.


Question 3


This issue is same as Question 2 but this time it is R3 which causes the issue. We can check R3 with the “show running-config” command.


Question 4


In this question we should check the local routers to see if these subnets have been advertised or not as there are many issues in the path which prevent these subnets from being shown in the routing tables.

When checking Branch1 router, we notice “network” is missing under EIGRP 200 so answer D is correct.

    Hi @MGL,

    Are the labs you indicated labs which you need to configure or some are multiple choice? Thanks. :)

    Hey guys did my exam today and passed. 53qns in total.
    Lots of labs about 8 or 9….most of the scenarios are similar but the problems are quite different and need you to be more keen.
    Take note of the drag and drop for QoS and BGP.

    do you feel lab in 9tut are enough for the answering the question? did the labs in 9tut cover all the troubleshoot command? i have my exam in 5 days. do u suggest to look for few more lab simulations?

    for other multiple choice and drag and drop, do we need to practice some other dumps?
    please respond. as i have exam in 5 days, i want to know, how difficult the paper was? and whether 9tut explanation is all we need to focus?

  22. Sinix

    Hello 9tut, I noticed that some sims do not have the packet tracer file to practice, like this one.
    Is the file available? Thanks

  23. QK
    April 24th, 2018

    To cathorine…

    yes the 9Tut labs cover all the that you need if, you understand the concept and how to troubleshooter the lan sims, for the labs that need for command or configuration, mostly are the same. just would like to say, you will pass for sure, if you do well with all labs and D&D. good luck in yr exam

    in question 1 why is None of the internal routes other than locally connected appear in the routing table I think the first command to issue is “sh ip eigrp neighbor” to see if there are any hello packets received at the local intrerface which there is none. then now you can go ahead and troubleshoot the local interfaces..
