Ticket 1 – OSPF Authentication

May 6th, 2018 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 10.1.1.1 255.255.255.252
 ip nat inside
 encapsulation frame-relay
 ip ospf message-digest-key 1 md5 TSHOOT
 ip ospf network point-to-point
!
router ospf 1
 router-id 1.1.1.1
 log-adjacency-changes
 network 10.1.2.0 0.0.0.255 area 12
 network 10.1.10.0 0.0.0.255 area 12
 default-information originate always
!

Configuration of R2:
interface Serial0/0/0.12 point-to-point
 ip address 10.1.1.2 255.255.255.252
 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.

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

OR

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.

    @goodluckmas
    start with:
    trace 209.65.200.241 so 10.2.1.1 => stop in 10.1.1.9 (host unreachable) => R3 don’t now route from R2 => why? => R2 “show ip ospf neighbor” => no neighbor R1-R2 (only R2- R3) => check why? => “show run int” on both routers => Bang! => Authentication problem!!!

    In TShoot Exam’s CLI,
    Can We Use PIPE for Filtering Commands.
    Like
    Show Running-Config | inc message-digest

    I failed the Tshoot Exam due to Internet Problem at the Testing Centre.
    These TShoot Exam Tickets are Heavy to Load and with Slow Internet
    Connection, It can be real messy and Ping/Show Responses are mis-leading.

    Testing Centre/Proctor raised an Incident and Pearson VUE will take 3 – 5 days
    for Exam Voucher or refunding the money.

    BTW, I scored 750 on 8 Tickets + MCQs + BGP Lab.

    Nitpicking here but the key shown in the example is using zero’s and not O’s (TSH00T instead of TSHOOT). Anyone copying and pasting the commands would still not form an adjacency.

    HI GUYS, I HAVE ONE QUESTION PLEASE.
    IN THE EXAM DOES THE TICKETS ARE NAMED? FOR EXAMPLE TICKET 1 OSPF AUTHENTICATION OR IT JUST SAY TICKET 1?
    PLEASE ANSWER

  21. Xanne

    @TACCACS+
    They are named just Ticket nothing more. You have to figure it out yourself if it is IPv4 or IPv6 and what kind of problem it has.

    @Xanne

    Thank you very much.
    As it’s 3 questions per ticket, are you allowed to use “PREVIOUS BUTTON” once you clicked on “NEXT” ?
    SIMPLY, IS IT LIKE SIMLET QUESTION?

    hi Guys,

    in this OSPF authentication ticket for R1. answer says serial 0/0/0 . but when I work on packet tracer I had to configure this command under serial 0/0/0.12 for OSPF to comes up.

    i’m not sure does packet tracer has bug or the answer should be Serial0/0/0.12 ?

    please verify.

    Took the CCNP TSHOOT today and did not pass. The way the labs are setup to seek out the issues are different; it appears there may be multiple issues that are presented in one lab e.g. I noticed on 4 of the labs R2 interface Serial 0/0/0.12 had the IP OSPF Authentication message-digest command while it was missing on R1 which led me to believe this was the issue but after the 3rd lab I knew this must be wrong so I started to TS other areas to find the fault. It makes more sense to TS the lab from Work-Station to SW then RT. I don’t find the flowchart TS example to be accurate to the lab changes. The latest (September 2019) MCQ from this dump were also on the test
