Ticket 1 – OSPF Authentication

March 30th, 2015 in TSHOOT v2 Go to comments

1.Client is unable to ping R1’s serial interface from the client.

Problem was disable authentication on R1, check where authentication is not given under router ospf of R1. (use ipv4 Layer 3)

Configuration of R1:

interface Serial0/0/0
 description Link to R2
 ip address
 ip nat inside
 encapsulation frame-relay
 ip ospf message-digest-key 1 md5 TSHOOT
 ip ospf network point-to-point
router ospf 1
 network area 12
 network area 12
 default-information originate always

Configuration of R2:
interface Serial0/0/0.12 point-to-point
 ip address
 ip ospf authentication message-digest
 ip ospf message-digest-key 1 md5 TSHOOT

Answer: on R1 need command ip ospf authentication message-digest”

Ans1) R1
Ans2) IPv4 OSPF Routing
Ans3) Enable OSPF authentication on the s0/0/0 interface using the “ip ospf authentication message-digest” command.


There are two ways of configuring OSPF authentication:

interface Serial0/0/0
  ip ospf message-digest-key 1 md5 TSH00T
router ospf 1
  area 12 authentication message-digest


interface Serial0/0/0
  ip ospf authentication message-digest
  ip ospf message-digest-key 1 md5 TSH00T

So you have to check carefully in both interface mode and “router ospf 1”. If none of them has authentication then it is a fault.

    Hi all,

    Does anyone of you guys who took the exam still remember how your IPV6 questions were worded? I got 3 IPV6 questions and all of them were worded as follow:

    IPV6 Loopback Address of R1 cannot ping IPV6 Loopback of of DSW2.

    Kindly confirm if this is how your questions were worded, and you answered them as instructed here by networktut?
    I failed with 820 points.

    Thanks in advance.

    Exam on 25/01/2018 with a negative result.On routers worked only the commands: ping, traceroute and show.Someone can explain to me why I could not get into the console to configure? I do not understand that I’m wrong?

    Are the routers/switches suppose to load on the simulator? Mine doesn’t. Is that normal?

    According to the diagram, R1 and R2 have serial 0/0/0.12 interface, however in CLI R2 is showing serial 0/0/0.12 but not on R1, is this an error ?

    Guys, read the main instructions..https://www.networktut.com/tshoot-faqs-tips.

    You cannot configure Trouble tickets in the exam. You can do show commands and verify and select the answers.. Here is the demo for trouble tickets..http://www.cisco.com/web/learning/le3/le2/le37/le10/tshoot_demo.html

    Thats not an error. The R1 interface is not sub-interfaced and this is also a way to connect/configure

    Anonymouse, for IPV6 you have to check the following: make sure it’s distributed in R4, Make sure in R3 the tunnel mode is not ipv6, Make sure IPv6 ospf is enabled under serial internet.

    I am taking the exam next month, Are these Tickets Still valid on the Tshoot Exam?

    In my understanding “network area 12” (under router ospf1) is also missing on R1 for bringing ospf up, is it a bug ?

    I also think that the network statement under ospf 1should be area 12 and not

    If you can ping but not, it means there’s an issue between them. You can issue command ‘show ip ospf neigh’ to check your ospf neighbor relationship. If there’s no neighbor relationship formed, then it means that there’s a problem with your OSPF configuration.

    I took and passed exam yesterday. All question are the still the same.

    March 4th, 2018

    On these tickets 1 through 16. Do you actually have to go there and config stuff and fix the issue or these are just Simlet and you have to pick to the correct answer. I think is latter,but I want to confirm.

    @TSHOOTER, u can enter show command to check the issue, but u only can choose the answer from the drop down list. Each ticket will have 3 question. What device, what technology and what solution.
