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.

    Just passed tshoot exam. Score 870/1000
    It was not so easy. A lot of new questions MCQ and a very hard iBGP & eBGP Sim. On this one there were two AS. Your duty is to console R1 and fix the issue. The iBGP & eBGP are in idle state.
    Also I had a problem in a ticket. I’ve left a comment.
    Apart from that everything worked just fine.

    Passed exam today 975/1000. Thanks to Ahmad elrofei. All that he gave came. But exam pattern has been changed. It’s not like we have to choose tickets. But it’s coming one by one,like other CCNP exams. Check in top right corner to see , in which question you are.
    Also there is a bug in ibgp/ebgp sim.
    Able to remove neighbor command and fix ebgp issue.
    But unable to rewrite/remove neighbor ibgp remote-as 64550. Even if u remove this command it’s not removing. I asked examiner, she told I need to contact Cisco. So I just added a comment to that question, which is available in top left corner. And did below and gave next.
    Router bgp 64520
    Corrected neighbor IP for ebgp
    Neighbor ibgp peer-group
    Neighbor ibgp remote-as 64520
    (Above will be like extra command in that bgp)
    All the best folks!!

    So… Why in the OSPF Auth ticket does DSW1 trace end at I am seeing that R3 doesn’t have a default gateway, but it is still neighbors with R2 under the RID. That RID is R2, shouldn’t this trace be failing at R2? Is this how the test works?

    @networktut Network between R1 and R2 is not being advertised by R1 in ospf area 12. Isn’t that going to be a problem for client 1 not being able to ping the server?

    February 24th, 2017

    So… Why in the OSPF Auth ticket does DSW1 trace end at I am seeing that R3 doesn’t have a default gateway, but it is still neighbors with R2 under the RID. That RID is R2, shouldn’t this trace be failing at R2? Is this how the test works?”

    I have the same question and i have not figure this out yet.
    Thank you

  46. paco
    May 6th, 2017

    Does it have to do with the area type of R4 that will generate a default route no matter what?

    I’m guessing that once the authentication between R1 and R2 breaks they will not exchange the default route which will reflect on R3. But then because you an NSSA area you have R4 with a default route to .9?
    Anybody that can shine some light on this will help a lot.
    Thank you

    May 25th, 2017

    DSW1 trace ends at – since Router R3 doesn’t have any (North going) “Default Gateway”, simply because the OSPF “Default Information Originate” Command on R1 has NO effect within THIS Ticket, since Router R1 / R2 has NO OSPF Routes between them, due to the missing / troublesome (OSPF) MD5 Auth. among the two routers (R1/R2)!
    Hope this helps!?

  50. Joe
    May 25th, 2017

    And YES, because of the OSPF NSSA area between R3/R4, you have a Default Route from DSW1 towards -> the outgoing I/F on R4 (via R4 ingress I/F: within the actual traffic Path! -That’s correct!
