OSPF Evaluation Sim
You have been asked to evaluate an OSPF network and to answer questions a customer has about its operation. Note: You are not allowed to use the show running-config command.
Although in this sim we are not allowed to use “show running-config” command but we post the configuration here so that you can understand more about the topology.

Some notices from above configuration:
+ The OSPF network type between R2 & R3 is non broadcast.
+ R3 and R4 is running virtual-link to connect Area 2 & 3 to Area 0
+ Area 2 is a NSSA area while Area 3 is a Totally Stubby area
You can download this sim to practice at http://www.digitaltut.com/download/ROUTE_OSPF.zip. Please use GNS3 with version older than v1.0 to open it (v0.8.3.1 for example). IOS used in this lab: c3640-jk9s-mz.124-16.bin
Question 1
Explanation
To check OSPF LSA we should use the “show ip ospf database” command on R5:
In this sim there is no LSA Type 4 because there is no ASBR so maybe this question wants to ask about LSA Type 3 (Summary Net Link States).
Note: LSA Type 4 is generated by ABR, not ASBR but without ASBR inside the network there are no LSA Type 4 generated. For more information about OSPF LSA Types please read our OSPF LSA Types Lab tutorial.
R3 advertises LSA Type 1 to R4 then R4 converts it into Type 3 and sends to R5 (because R4 is the ABR) so we see the “Link ID” 3.3.3.3 of R3 is advertising by R4 (4.4.4.4). According to the “Age” column, this LSA was advertised 1858 seconds ago.
Question 2
Explanation
Check the Serial1/0 interface of R3 which is connected to R2 with the “show ip ospf interface serial 1/0” command:
There are two things we should notice from the output above:
+ The “network type” connection between R2-R3 is “NON_BROADCAST” (usually we have “BROADCAST”). OSPF neighbors are discovered using multicast Hello packets. In non broadcast environment, multicast (and broadcast) messages are not allowed so OSPF neighborship cannot be formed automatically. Therefore we have to establish OSPF neighborship manually by using “neighbor ” command under OSPF process (OSPF will send unicast Hello message to this address). For example on R2 we have to use these commands:
| router ospf 1 neighbor 192.168.23.3 |
And on R3:
| router ospf 1 neighbor 192.168.23.2 |
+ For non broadcast environment the default Hello timer is 30 seconds; Dead timer (time to wait before declaring a neighbor dead) is 120 seconds and Wait timer (causes the interface to exit out of the wait period and select a DR on a broadcast network. This timer is always equal to the dead timer interval) is 120 seconds. In the output we also see the default timers for non broadcast network.
Question 3
Explanation
We can check the number of executed SPF algorithm via the “show ip ospf” command on R4:
In the output above we can see SPF has been executed 9 times.
Question 4
Explanation
Area 2 (of R5) is a Not-so-Stubby area (NSSA). You can check it by the “show ip ospf” command on R4 or R5 (in Area 2 section). For example, below is the output of “show ip ospf” command on R5:
In general, NSSA is same as normal area except that it can generate LSA Type 7 (redistribute from another domain) so we can see both Loopback interfaces of R5 & R6 in the routing table of R5.
Note: NSSA does not receive a default route by default so you will not see a default route on R5.
Area 3 (of R6) is a Totally-Stubby area so R6 only has one default route to outside world. You can check with the “show ip ospf” command on R4 and R6 (area 3 section):
Notice that on R4 you will get more detail (shows “stub area, no summary LSA”) than on R6 (only shows “stub area”).
R6 is in a totally-stubby area so we will not see any R5’s Loopback interfaces in R6 routing table:
Note: You can see a default (summary) route to the outside (O*IA 0.0.0.0/0 …)

Hello @malik
Could you please send me the valids dumps? lilianbeti @ gmail.com
Tks!
I just pass the exam
all from 183Q passleader +41
labs are all the same except OSPF Sim , it is not asking to do Stub it is just normal OSPF configuration do show run and see the missing networks and add it then do ping to the loopback
all 3 choices are there in exam randomise focus more on three choices
chap Drag and drop , thanks all except to those who didnt reply to my mails
hurry up and take it quickly

Hi guys, I have passed my ccnp routing exam yesterday at (23/1/2017) with score (973), actually the dumps of 149q and 41q tagwa is still valid.
Most the question came from the 41q tagwa, so you have to study it very well,
BUT it important to study also the dump of 183q/32q/8q because it contain a lot of questions that you will not find them in both 149q and tagwa 41q dumps, in my exam none of new questions of 183q/32q/8q came, but I recommended to studied any way
The sim in my exam:
-ospf eigrp redistribution
-ospf evaluation
-ospfv3 with virtual-link
-ospf sim
-policy based routing sim
The drag and drop:
-CHAP drag (in tagwa 41q)
Important notes about the sims:
Regarding to sims , you should be careful because you might find that there some minor changes in the sims (like ip addess, subnets , ospf process numbers , eigrp autonomous number and so on) so check with show run command if that possible before starting the configuration, don’t not rush to configure blindly .
In my exam, there was some little change in ospf evaluation, I mentioning below the question with changed answer:
The question:
Which of the following statements is true about the serial links that terminate in R3?
A. The R1-R3 link needs the neighbor command for the adjacency to stay up
B. The R2-R3 link OSPF timer values are 30, 120, 120
C. The R1-R3 link OSPF timer values should be 10,40,40
D. R3 is responsible for flooding LSUs to all the routers on the network.
In dumps sim you will find that the correct answer is B, but in my exam that was not true, because I found that the exam changed the link R2-R3 timers to 10,40,40 and it was point-to-point link.
also I found The link R1-R3 timer was 30,120,120 non-broad cast link, so both of the answers A , B are wrong .
Also D was wrong because, R3 was not the DR in all the links,
The right answer was A, because the link R1-R3 is non-broad-cast link so neighborship should be configured manually.
So it is important to be carful .
Important notes about tagwa 41q dump:
It is important to mention that in tagwa 41q dump there some questions with wrong answers, here below I mentioned the question with the wrong answers:
Question 2
Refer to the following configuration command.
router(config)# ip nat inside source static tcp 172.16.10.8 8080 172.16.10.8 80
Which statement about the command is true?
A. Any packet that is received in the inside interface with a source IP port address of
172.16.10.8:80 is translated to 172.16.10.8:8080.
B. Any packet that is received in the inside interface with a source IP port address of
172.16.10.8:8080 is translated to 172.16.10.8:80.
C. The router accepts only a TCP connection from port 8080 and port 80 on IP address
172.16.10.8.
D. Any packet that is received in the inside interface with a source IP address of 172.16.10.8
is redirected to port 8080 or port 80.
Answer:A
Tagawa say the right answer is A , but that wrong the right answer is B (this question came in my exam)
—
Question 28
A network engineer wants to ensure an optimal end-to-end delay bandwidth product. The delay is
less than 64 KB. Which TCP feature ensures steady state throughput?
A. Window scaling
B. Network buffers
C. Round-trip timers
D. TCP acknowledgments
Answer:A
Also that wrong the right answer is B
For the dumps, you can send me at ahmedrofaii at gmail dot com , I will be glad to send them to you freely , for routing dumps and for switching , tshoot dumps
I wish for you good luck in your exam 3
no window scaling is the correct answer
Hi Ahemed,
It makes sense that this is the right answer … I do not understand why not!
A. Any packet that is received in the inside interface with a source IP port address of
172.16.10.8:80 is translated to 172.16.10.8:8080.
Can someone please send the valid dumps 300-101 davidkeys @ twc.com
