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
 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.

    start with:
    trace so => stop in (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!!!

    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.
