Ticket 1 – OSPF Authentication
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.
Hello all,
Concerning the Ticket 1(OSPF Authentication) and following the giving configuration and following the premium access i have, the issue is not related to ospf authentiction but issue ie coming from the ospf bad network statement configured in ospf prcess in R1
any comment please?
Thanks
Has anybody noticed on the actual exam that Router 2 shows “Area has no authentication” for Area 12 when it should show message digest authentication? Did I mis-see that in in my exam?
Hola
rendi el Tshoot antiguo hace varios años atrás. En el actual se puede usar “tracer” desde el PC? o solo desde los Routers, o simplemente no se puede usar tracer?
de antemano gracias.
Put “i” in start of my name and you will get download the file.
guys, I passed the exam today, I got same Tickets as in this file.
Creo que “tracert” no funciona desde el Client1 pero realmente no lo necesitas.
Passed the exam today with 925! Pay the premium membership, then you will be able to see the Multiple choice questions and get access to the ticket online simulator! Everything is the same in the exam. The only questions on the exam are the november questions. Thank you so much networktut. this was my last exam, i’m a CCNP!! Im so happy!
Good afternoon @Anon, you recommend that I become a premium for the exam, I do it on February 19.
Can Anyone lend me his/her Premium account credential just for 1 or 2 days?

If you can’t afford $22 to study for a couple days I don’t know how you’re going to afford $300 for the test.
how many questions in the premium account,
is it too much like routing and switching
The network statements are mis-matched in this config.
R1:
network 10.1.2.0 0.0.0.255 area 12
network 10.1.10.0 0.0.0.255 area 12
Doesnt enable the interface toward R2.
Regardless of authentication An OSPF neighborship would never form.
interface Serial0/0/0
description Link to R2
ip address 10.1.1.1 255.255.255.252
please correct me if I am wrong about this.
