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.

    Hello NetTut, R4 should not have learned via ospf because there are no ospf neighbors between R1 and R2 and R1 is the only one who advertises default route into internal network via OSPF with “default-information originate always”

    If you do a traceroute from DSW1 to the WEB Server, it will show you that the trace is working up to of R3. However, that traceroute should be going one hop further. It should really stop at of R2. I think it is an error in this simulation. And that error can mislead somebody into thinking that the problem lies between R2-R3 but it really isn’t.

    hello. im a new premium member. this question is a bit confusing. the ospf neigh is not forming on R1, so it is ospf problem. however, it CANNOT BE the authentication, because both routers have the correct settings/syntax. however, the network statement in R1 doesn’t include it’s serial area 12, and so i thought the correct answer was to configure R1 with area 12. was this a typo?

  21. networktut
    October 2nd, 2017

    @mdee: Note:

    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.

    Took the exam 6/10/17 and everything on this website is correct. Fantastic work Networktut.com. You would have to be beyond CCNP level to easily solve all the problems inside two hours. Help from sites like these is essential for most people.

    Took exam today..Failed.
    The answers to the faults are already present in the tickets. Eg BGP Ticket already has correct IP but for question has an option to change IP from 56 to 65 and few other options which are not even related. Please let me if if its ok to leave the fault answer as open and close the ticket i mean with answer the 3rd question can we still mark ticket done because in BGP case the IP was correct in show run

    Yea! You have possibility to return to the previous question and change it
    but for each your new answer it’ll be available different variants of answers for next question (“tree” scheme). Ticket validation is required only when You are sure found the correct answers.
