OSPF Sim
Question:
9tut.net company has decided to network three locations to improve efficiency in inventory control. The routers have been named to reflect the location: Boston, Frankfurt, Lancaster.
The necessary networking has been completed at each location, and the routers have been configured with single area OSPF as the routing protocol. The Boston router was recently installed but connectivity is not complete because of incomplete routing tables. Identify and correct any problem you see in the configuration.
Note: The OSPF process must be configured to allow interfaces in specific subnets to participate in the routing process.
Answer and Explanation:
The question mentioned Boston router was not configured correctly or incomplete so we should check this router first. Click on PC-B to access the command line interface (CLI) of Boston router.
Boston>enable (type cisco as its password here)
Boston#show running-config
First, remember that the current OSPF Process ID is 2 because we will need it for later configuration. Next notice that in the second “network” command the network and wildcard mask are 192.168.155.0 and 0.0.0.3 which is equivalent to 192.168.155.0 255.255.255.252 in term of subnet mask. Therefore this subnetwork’s range is from 192.168.155.0 to 192.168.155.3 but the ip address of s0/0 interface of Boston router is 192.168.155.5 which don’t belong to this range -> this is the reason why OSPF did not recognize s0 interface of Boston router as a part of area 0. So we need to find a subnetwork that s0 interface belongs to.
IP address of S0 interface: 192.168.155.5/30
Subnet mask: /30 = 1111 1111.1111 1111.1111 1111.1111 1100
Increment: 4
Network address (which IP address of s0 interface belongs to): 192.168.155.4 (because 4 * 1 = 4 < 5)
Therefore we must use this network instead of 192.168.155.0 network
Boston#configure terminal
Boston(config)#router ospf 2
Boston(config-router)#no network 192.168.155.0 0.0.0.3 area 0
Boston(config-router)#network 192.168.155.4 0.0.0.3 area 0
Boston(config-router)#end
Boston#copy running-config startup-config
Finally, you should issue a ping command from Boston router to Lancaster router to make sure it works well.
Boston#ping 192.168.43.1

Other lab-sims might appear in the real ICND 2 exam, read and understand them if you have enough time!
Passed ICND2 today!!!
Every questions came from this dump.
http://www.examcollection.com/cisco/Cisco.ActualTests.640-816.v2010-02-08.by.CrazyHunter.vce.file.html
Got the OSPF and VTP lab from 9tut.
Just took the icnd2 640-816 exam and passed with 917. I got a question simular to this (same layout and OSPF area), but I really struggled with this question (probably would have scored much higher). The quesion was sort of “Boston router exists on the network. Frankfurt and Lancaster are added to the network but users are experiecing communication problems” Not exactly but something like that. Anyway, I poked around to try to troubleshoot this and found that Lancaster was not showing any routes in #sh ip route. I saw (#sh run) that one of the networks were config’d to area 1 instead of 0 so I removed “no network” and put back with area 0 which fixed that but I didnt’ see any other issues on the other routers. I’m sure I missed some points on this one. It was hard moving around in theri querkie interface and I was panicing.
Some of the multiple choice came from Testinside but not alot (not sure if they changed the test recently).
SIM were only 2 – This one and the VTP. No drag and drops at all.
I was sweating this one and wasn’t sure if I would pass because I bombed this SIM but 917… I’ll take it. Good luck to all.
I just looked at my score for this SIM and I only scored a 73% so I definately missed some stuff. Oh well at least I passed. I was running out of time and this was 3rd to last question so I just moved on (41 questions 1:15 mins). Anyway I still passed but I know I could have scored higher if I only had the time.
I see a second mistake on router Lancaster. The interface s0 got the ip adress 192.168.155.9 this a NETWORK ADRESS. It must be 10 and 11 to work properly.
With the subnet mask of /30, the increment is 4 so 192.168.155.0, 192.168.155.4, 192.168.155.8 and 192.168.155.12 are the network addresses. 192.168.155.9 is the first usable address in the 192.168.155.8/30 sub-network.
Took ICND 2 today, didn’t have any of these.
hey none, what did u get on the test? im about to take it and i took it 3 weeks ago.
I studied the test-inside and took the exam but failed miserably. Went to test-king.com and they just recently updated there study guide as of 8/31 for the ICND2 and noticed a lot of the questions that I missed on there. I am going to study it this weekend and take test soon so I will know better. The only one I did not see was the Lab of the East and West switch that you had to configure ip address etc but I could not find any other addresses to go off of so I was frustrated at the time and blew that one.
upload the test-king plz
Took test today 9/6 was not on there only had VTP lab sim.
Has anyone gotten a slightly different OSPF sim on ICND2?
way changed!!!!. becareful.
VTP / OSPF / NAT/ ACL I never seend before.
H, eveyone ,has the vtp/ospf/nat/acl changed that much.I have been useing Pass4sure and How2pass, which is the best because it has all the interactive sim’s that you can practice.I pass icnd 1 and the sims were exactly like the test.It cost just $30 and has everything you need.Does anyone know if the test has changed.I am going to test foe icnd2
tommorow and was wondering.
@gwbaby so what was changed? any tip for us exam takers.
Hi, everyone i need to exam icnd2 after 2 weeks is there any change in the exam questions please help me
Hi , taking ICND2 tom, I too have been studying books, latest p4s and labs from how2pass and this site, has the vtp,ospf,nat,acl changed and will I expect to see them all in my exam tom.

Hi, everyone, anyone have How2pass dumps and lab/simlets, kindly send the link, I will take my ICND2 in two week. thanks
Taking my ICND2 test tomorrow, 10-27-10, wondering if anyone has taken the test recently and whether the sims have changed a lot or if they are some what the same. Any help would be great.
Took today, none of these labs were there
nice.. thanks
This blog appears to recieve a good ammount of visitors. How do you get traffic to it? It gives a nice individual spin on things. I guess having something real or substantial to post about is the most important factor.

THANKYOU.
exam hi everyone m taking my icnd2 exam on the 2nd february, please forward me any new sims @ skgomotso@hotmail.com
Just passed the 822 test last week and now looking at the 816. Looking at some of the test question there seems to be a lot of overlap. So, can anyone tell me if any sims from the 822 will be on the 816?
Also any other info will be good to know.
morrisgl@aol.com
Took the exam last week. Had this OSPF Sim. Remember to copy run/start and ping to get full credit!
I took my 640-822 yesterday and failed with 811 points, i had 40 questions containin 2 sim. One was to assign i.p address, default-gateway and change the switch to a vtp client. A well config. Switch was connected to de new switch. Will i pay another $125 if i wanna re take ?
@A bad day Yep, you should pay again for retake
Does anyone have a packet tracer sim for this question?
Does anybody know if the ping at the end scores any points in the exam?
similarly with the vtp sim are there any points for saving running config to startup and pinging the router?
thanks in advance
Why did you use the command
network 192.168.155.4 0.0.0.3 area 0
instead of just
network 192.168.155.0 0.0.0.255 area 0
I understand that this way the mask is a bit larger than needed, but it won’t cause any issues, would it?
Hey where is the lab file to download ? cheers
Congrats to all that have passed!!! Be Proud!
If there is a MIGWIZ that has passed already…could you please send me the Packet Tracer SIMS for: VTP / OSPF / NAT/ ACL.
SEND 2 EMAIL: ajvash@hotmail.com
Thank you, and God Bless!
hi fri i have clear t exam in 2day my score 974, thax 4 9tut
Have my 3rd attempt in 6 months on icnd2 tomorrow, was hoping to get any packet tracer sims for VTP/ospf/Nat/ACL if anyone has. Please send to
Cramit420@gmail.com
Any help is appreciated
best wishes, my friends — i take the ICND2 in two days. wish me the best of luck! long live 9tut.com!
Hi 9tut about the Sim shown above does the below statement have any impact on answering the sim question.
Q. Does OSPF form adjacencies with neighbors that are not on the same
subnet?
A. The only time that OSPF forms adjacencies between neighbors that are not on the same
subnet is when the neighbors are connected through point−to−point links. This may be
desired when using the ip unnumbered command, but in all other cases, the neighbors must
be on the same subnet.
The question was:
Why did you use the command
network 192.168.155.4 0.0.0.3 area 0
instead of just
network 192.168.155.0 0.0.0.255 area 0
I understand that this way the mask is a bit larger than needed, but it won’t cause any issues, would it?
Answer:
Because then you would be advertising the whole of the 192.168.155.0 range instead of two addresses. You might want to use VLSM and use those addresses else where in your network. I’m not sure if the 0.0.0.255 would be wrong for this particular test question, but if the other serial links are using addresses in the 192.168.155.0 255.255.255.0 range, it wouldn’t work and your answer would be wrong. Best to stick with the 0.0.0.3.
One question from my side. Is it wrong to configure it this way?
network 192.168.155.0 0.0.0.8 area 0?
Please tell me. my email id: kp_lt@yahoo.co.in
@rupul
It will be correct if you consider 1st subnet i.e. subnet zero
Hi 9tut guy i have got packet tracer lab for this ospf sim (with answer) and want to give it to u so tht u can post it here…how can i send it to u
Hi Jithin, would you email to me – tony@ hyus com. Many thanks!
Hi Jithin, would you email it to me also – datsig88@hotmail.com
Hi, Jithin, could you send me the packet tracer ospf lab. My e-mail is garciga.alejandro@gmail.com. Thanks a lot.
is it really that hard for you guys to build the lab on your own?
Gotta agree with xallax, if you cant build the sim based on the Image and info provided you dont need to be taking this exam!
Hey I just gave the exam and scored 947. I want to THANK EVERYONE who helped put up this site and all the users with their invaluable comments. You guys are awesome. GOD BLESS YOU.
Thank You.
Hi jithin, would you email it to me pls.. – rchucas@hotmail.sg
congratulation, Rocky.
Greatfulness is a noble virtue. But, It is better to put some information on the exam’s questions. It should be more helpful and agreable for us who are preparing for the CCNA ( ICND 1 and ICND 2 ) exam.
Thankyou.
