IPv6 OSPF Virtual Link Sim

All sims are similar to what you see on this website , but most of the multiple choice are different …loads of DMVPN , TCP/UDP , IPV6 and simlets

Cool guy, the area between AREA-0 & AREA-54 is AREA-11. That is the transit area, not 54.

Re: Cool-Guy
Think of it this way; Area 11 is just fine because it has at least one router in the backbone area 0, the virtual-link command is technically merging area 54 with area 11 so as to satisfy the condition of having at least one interface in the backbone area. That is a good way to look at it.
Let me know if this helps you

Anyone who took the exam recently can confirm which are the SIMs in the exam?????
I’m gonna take it early next week.
Please respond asap.

Thank you FRANKIE

Just added all of the Labs into one big GNS3.. hit me up if you are interested>

@ all, please help:

When I do on R3: no area 54 virtual-link 4.4.4.4 and on R4 no area 54 virtual-link 3.3.3.3

Than I cannot ping FEC0:4::4 and I cannot see it with show ipv6 route ..

Why? Is the GNS3 Lab wrong?? Please help

about the show ip route on IPv6 OSPF virtual link. why FEC0:4::4 does not appear on R1. I follow all of the steps that written here on this site. PLEASE HELP..

@hacker: Look the message from @frankie. Check Loopback0 on R1 and on R4 – they aren’t participate in an OSPF process.
So add ip ospf 1 area 0 for L0 on R1 and ip ospf 1 area 54 for L0 on R4.

@hacker: Sorry, a little mistake in commands:
ipv6 ospf 1 area 0 – on R1
ipv6 ospf 1 area 54 – on R4

show ipv6 ospf int – to check what interfaces are participating in an OSPF on this router for IPv6.

@frankie @Dim. Do we need to change the area assignments on these loopbacks? As the instructions says, we are not allowed to change the area assignments.
I changed the area assignments on the loopbacks and I can ping already. Is this true as well on the real exam? Or this lab has the wrong configuration?

@nowlad: Than I cannot ping FEC0:4::4 and I cannot see it with show ipv6 route ..

-> you should type these command in R1’s int l0 and R4’s int l0
interface Loopback0
..
ipv6 ospf 1 area 54

and
interface Loopback0
..
ipv6 ospf 1 area 54

@frankie @Dim. Do we need to change the area assignments on these loopbacks? As the instructions says, we are not allowed to change the area assignments.
I changed the area assignments on the loopbacks and I can ping already. Is this true as well on the real exam? Or this lab has the wrong configuration?

hi
I still dont understand why we need to lo0 of R1 to be in area 0 in order to ping lo0 of R4

I have downloaded the lab from here , all the routers are empty from configuration. why?

how can i downgrade my gns3,i cant seem to open any of the GNS files shared due to version incompatibility,any idea please.I cant find old GNS3 versions anywhere.

Hi
any one have real exam GNS Lab Sim for all labs?

can you provide me the IOS Image which can open this virtual link ospf lab in gns3. PLSSS

I don’t know why R1 receive R2 and R3 loopback ip routes without configuring them in ospf process and it is needed to include R4 and/or R3 loopback interface in ospf process in order to receive in R3/R4. Any idea?

Also, why it is not receiving R1 routes of Fastethernet of R4 or Serial of R3?

If you were not able to ping R1 loopback address then it means the loopback interface was not added to area 0.

¿¿How do you ping between R1 and R4??

How to add ipv6 LOOPBACK address FECO:1::1 ON Cisco router
can someone show me and email me on syedmr4 at yahoo.co.uk

hello mujib,

on the very interface

R1(config)#int f0/0
R1(0nfig-if)#ipv6 ospf 1 area 0

it just a example for you

had a weird experience in the exam with this lab: as soon as I took out the unneeded virtual-link between R4-R3, the neighbor adjacency went down yet the loopback from R4 would show up in R1. Even after the correct virtual-link came online, there were no Neighbor FULL status messages, yet if I put the unneeded virtual-link on there, I would get the syslog for Neighbor Full.

the sim for ipv6 ospf virtual-link dont work
can you fix the probleme

9TUT is the best. I see people asking for dumps here and there, others complaining about outdated questions. Worse, some other folks come here to advertise their unpopular websites (shame on you). Please STOP IT. For test takers :

Exam questions are part of a pool of questions. Some questions have 2 or more reformulations, thus memorization will not help for all questions.

– Read the official certification guide and understand the concepts (search cisco press articles to get deep knowledge on certain topics).

– Do as much as labs you can. Familiarize with the output of the most important commands, the correlation between commands and the correlation of a command with the concepts.

– Come on 9TUT and spend 2 to 3 weeks. Caution : I strongly believe that some questions do not have correct answers. Thus, I advise that you validate with further readings (this will also allow you to be ready with reformulated questions).

Bingo, you got it. I passed with a score of 900 (3 sims : OSPF Virtual link, OSPF EIGRP Redistribution and EIGRP stub).

For the redistribution, its a 3rd case (because there are 2 ethernet links : between R2-R3 and R2-R4). Traffic had to go via the shortest link. I applied the 9TUT Case 1 config.

Good luck.

IPV6 OSPF Virtual -Link lab

Configuration of R4 as its stated that to get full marks disable this command
area 54 virtual-link 3.3.3.3

if we disable this we cannot ping from R1
If we disable this command then There is interface loopback 0 we have to assign area 54

Final step should be R4#configt –R4#(config)interface looback 0 –R4(config-if)#ipv6 ospf 1 area 54

once that is done R1#show ipv6 route (FEC0:4::4 should now show up in the routing table)
#SHARKTANK

interesting test i did and found another possible solution, just make area 11 a virtual link:

On R2:
area 11 virtual-link 3.3.3.3

On R3:
area 11 virtual-link 2.2.2.2

For this to work R4 would have to have its Loopback interface in a different area and would have to have area 54 configured as a virtual-link, but since R4’s config is not shown can’t know for sure.

So check R4’s config for the following:

R4
interface loopback 0
ipv6 ospf 1 area 55
ipv6 router ospf 1
area 54 virtual-link 3.3.3.3

if they exist on R4, just add the area 11 virtual-link on R2 & R3. After that R4’s loopback will show in R1 routing table and pings will work!!!

Hi, unfortunately I have failed the exam. Used the pass4sure material that can be renamed to fail4sure! If you are thinking on purchase these material, you better think twice.

The labls are quite the same. Just do the labs from here and you will be ready to do the labs in the real exam.

There are a lot of questions related to Frame-relay LMI, NAT-PT, NAT64, ACLs , A/A/A, mGRE, uRPF loose/strict and EVN.

is there issue with the lab as with above instructions we dont see the route added

I agree the GNS3 lab doens’t work if the basic virtual link commands listed here are done.
you have to add the L0 on R4 and L0 on R1 to ospf to make the routes appear and be pingable.
is this the same in the actual exam? or is this just a GNS3 Bug?

Dear Guys,
Yesterday I passed with 8XX the exam 300-101!! and this question was in the exam, regards from Peru.

@HansPeru Did you remove the virtual link on R4 and put loopback 0 in area 54 so the pings from R1 to R4 would work?

Or is the answer from digital tut correct as it is and there is no need to do anything further on R4 loopback?

Hi,
It was not necessary to add R4 loopback to 54 área (already it was in the configuration), so the loopback of R4 must be in area 54

@HansPeru So did you just use the configuration answer from digitaltut? Was there anything extra you had to do?

I had this sim today, realized that the exam did not allow me to conduct ping from R1 to R4 or vice versa. We will need to ensure R4 Lookback is in R1 IPv6 Routing table (show ipv6 route). Above exam is enough to pass this question.

Hi guys,

today I had the exam, passed it with 900.
There were about 15 to 20 new questions.
More than 7 Frame-Relay.
It’s not enough to just concentrate on pools but it helps.
It needs to understand the concepts and little more.

Labs were the same. No changes.

Thanks digitaltut.
Thank you guys.

@ CCNP how do you configure th OSPF virtual link?

I do ping from from R4 to R1 but it is not success, then I advertised the Loopback IPv6 of R1 in Area 0, then the ping success

missing conf on R1 & R4…that will make routes of R4 appear in R1
& R1 appear in R4

R4(config)#int loopback 0
R4(config-if)#ipv6 ospf 1 area 54

R1(config)#int loopback 0
R1(config-if)#ipv6 ospf 1 area 0

I configure IPv6 address and adverised it on R1 then the ping from R1 to R4’s loopback success

Took the test. Had this lab. But here is the strange part, R1, R2, R3 and R4 ethernet interfaces were configured with ipv6 addresses, however, interfaces (Serial) between R2 & R3 are configured only with ipv4 address, not ipv6. I tried configuring ipv6 autoconfig on the serial interfaces, but it wouldn’t take the command. Did anyone else notice that the Serial interfaces were using ipv4 addresses? Looking at the configs I did not notice any type of translation being used between ipv4 and ipv6.

Hello everyone,
Anyone have CCNP route dump can please help to send me at gmail:
. I will be very appreciate and thanks a lot. Thank you.

does anyone have an answer to Anonymous Question on Dec 20th 2018??

@Anonymous

did you try to configure a tunnel? or notice if there any tunnel or similar technology already in congif in exam?

@Anonymous

What I have noticed is that these are only simulations, not using the real IOS. So I took the exam, it had an ospf sim/lab. R1 needs to be able to ping loopback on R4, but initially you can’t ping R4 loopack. The loopback of R4 was shown on the screen for your reference, but I initially didn’t notice it, so to get the loopback ip, I clicked on the console for R4 and did a “sh ip int brief” to get the loopback ip, but there was NO loopback interface configured at all, then I finally noticed the loopback ip address shown on the screen (just below the summary description of the problem). So I figure, ok, I need to configure the loopback on R4. So on R4 I type “configuration terminal” and hit enter, but then I got a pop up box that said “Error, This configuration cannot be changed”. I thought that there was an issue with the test itself. So I tried to log into the other routers and there I was able to log into config t mode without any issue. So again I thought that there was something wrong with the test itself and I was about to go get the person who worked there to show him. But then on R4 I did a “show run” and in the config the loopback address was already configured. The simulation simply did NOT show the loopback interface or ip address when doing a “show ip int brief” (even though it showed the ethernet/serial interface and its ip address). So on R1 and R2 I just had to configure ospf and then I was able to ping R4.

So the moral of the story is, these sims are not real. If someone saw ipv4 addresses between R2 and R3 and no ipv6 address was configured and no translation was being done and no one else commented that they had to configure ipv6 addresses between R2 and R3, then more than likely, the ipv4 addresses were just a mistake that has no affect on whether you can get the virtual command/sim to work correctly. But this is something good to know, cause you could easily freak out and waste time if you don’t see something right, even though it really doesn’t affect your ability to do the sim.

The webmaster of this page should take what I’m saying and post it at the top of the lab sims and basic labs page so people are aware that this occurs on cisco’s tests.

@TutAdmin

lab is not responding to
R2#show running-config
This command is not supported on this device.
R2#

@TutAdmin

show run it staken the ful command is not.

One more question is this correct? or should be Area 0 instead of 11?

R1#sh run
Building configuration…

Current configuration : 794 bytes
!
interface Loopback0
no ip address
ipv6 address FEC0:1::1/64
ipv6 ospf 1 area 11

“After finishing the configuration don’t forget to ping between R1 and R4 to make sure they work well!”

“Now all the configuration was done. It is weird that we can’t ping the IPv6 loopback interface of R4 (with the ping or ping ipv6 command) but we can check by using the command show ipv6 route on R1”

In order to ping you have to advertise the loopbacks into ipv6 ospf process. Not sure if that is done on the exam. Will be taking it later this week.
