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.
You can download this lab and open with Packet Tracer here: https://www.9tut.net/download/OSPF_Sim_with_Solution.zip. Please say thanks to Renan who shared the files with us!
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

can anybody send me a vce player please. my email is kenneth.mulaudzi@yahoo.com
Hello All,
I’ve noticed there is no download .PKT file. So I’ve created this Lab SIM.

Good Luck to all candidates 🙂
Thanks Renan
thanks to Renan for the pkt tracers
Thanks Renan your awesomeness 🙂
always thought the OSPF process was locally significant ? not like EIG|RP which is the Autonomous system ID ??
#router ospf 1 – process id
#network a.b.c.d 0.0.0.0 area 0 – areas need to match for neighbours to work
The OSPF process ID is locally significant, however if you place networks into a separate process ID from the rest of your network entries it will not consider it a part of the existing routing process. For example using two different ospf process id’s on a single router you could have two separate area 0’s within your network environment.
Just passed the ICDN2 today, scored 990!!
Questions here are dead on however there are way too many that are no longer valid, for the latest buy pass4sure and you will be all good!
l
Later
Looks like Carlos works for Pass4sure.
THANKS RENAN! 😉
Thanks Renan!
Can someone please confirm if this SIM is still valid on the new ICND2.
I will let you know KOKE i
am taking the test on the 20th of january 2015
can anyone confirm that this is the same ospf sim with the same ip addresses? sitting exam soon.
no one has pointed out that you can just do a show run on router Frankfurt to get the ospf adjacency.
you still have to remove the network but it is a lot quicker.
router ospf 2
log-adjacency-changes
network 192.168.155.8 0.0.0.3 area 0
network 192.168.155.4 0.0.0.3 area 0
network 192.168.29.0 0.0.0.255 area 0
!
I appreciated to Renan
Please tell me friends….i heard that after 29th January 2015 the ccna exam course will b change…is it true ??????
Yea it seems it is true. I failed today. I think it is approximately 40% of the questions that were completely new ones.
thnx Renan

Took the test 19/5/15, there was an OSPF sim but it was completely different to this one. It was a testlet (no configuration needed).
ICND2 200-101 above 15 dumps are valid or expired?
Anybody currently given ICND2 200-101 exam with above dumps?
Find this helpful video related to ip addressing on youtube:

I was not able to get the pkt file Renan created to work. Packet Tracer becomes unresponsive.. Please advise!!
just follow the link for dumps
wurl. cc/dumps
This was on my exam today – scored 980/1000. Thanks 9tuts
What program file do I need to open a file 100-101vce from examcollection?
I can open it but its not readable.
wtf is this on ICND2 exam? I thought it was only Frame Relay and EIGRP lab sims…
check out the exam topics from the sisco website, i just don’t NAT and Access list, but you still have to know them cause they could be part of the T/S questions
passed ICND 2 today
know this sim
no need for dump, this site is all you need to pass!
what is the passmark ?
Anyone have a software to open the test (VCE) ?
Thank you, renan!
Hi all,its exciting reading the positive feedback on this forum.
I am also in line to sit for my ICND1 in less than a month.
DUMPS for ICDN1(and ICND2) would be greatly appreciated.
Thanx in Advance
In packet tracer, I have tried different OSPF related show commands. But none of them showing this problem “192.168.155.0 255.255.255.252”
How come ??’
Can’t we use other command to troubleshoot this problem ??
just had icndi 2 and passed with 960 most questions came from here. however, you must prepare sims as i had 2 sim one eigrp one frame relay both sim are explained above. But instead of having OSPF there was just 4 questions where you had to provide answer how many network will be installed on R1 if OSPF was config with classful mask the topology was based on 6 routers and networks of 172.162.
some of the questions were changed but if you study all tut and you get the idea then new questions will be answered without any pro
good luck
Could someone send me the latest Dump please
Bishopmike1218@me.com
Jay, my ICDN 2 is on the end of this month, how was yours, did you find all questions you expected according to 9tut or you had some different questions?
Got icnd1 easily without vce or 9tut. Its just a basic stuff.
Now doing icnd2 / next week and must say to all of you, 9tut is all you need for your ccna exams.
Read ccna books and use 9tut.
good luck all
I still understand and write Chinese, just not type fast engouh. Tell you guys with same name as mine, it is wonderful name according to the fortune-teller and I can be a witness too.
where can the dumps be downloaded from?
Please help!!!!!!!
my ccna will expire on december ,in order to extend do i must recertified with ICND2????? Right!
tank you!!
Great Explanation 😉
Are this questions and sims up-to-date?
passed ICND 2 today. most questions came from 9 tut. I had 2 sim: frame relay and ospf, just answer 4 questions!! Enter IOS commands to verify network operation and answer four multiple-choice questions. THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION. This is true. Thanks 9tut, good luck!
@9tut – There’s no sign in/sign up link anymore. What happened?
Did they refund you money? or ..

Hi, nice example about Open shortest path first (OSPF)..you can also use this…

I am going to Write the CCNA ICND1 exam on May 1st Week . Is all the dumps in 9tut are valid. Since I here that the Cisco will change the questions frequently . Please help !! I am very much tensed
Guys not buying the brain dumps. Some of the questions were on my exam. As a matter of fact about 30% of the questions were on the exam – I used the answers that were provided and still did not pass .
I should not rely on sites to help me as we should know the material. It is quite disappointing but for those of you wishing to continue to cheat – It is not worth it if you do not know the subject at hand!
anyone has the current dumps for ccda?
this is a great problem and answer.
Thanks
Peanut
I would have thought to only type SHOW RUN but I guess this is the short cut or alias of SHOW RUNNING-CONFIG
PT
