IPv6 OSPF Virtual Link Sim
Question
Acme is a small export company that has an existing enterprise network that is running IPv6 OSPFv3. Currently OSPF is configured on all routers. However, R4′s loopback address (FEC0:4:4) cannot be seen in R1′s IPv6 routing table. You are tasked with identifying the cause of this fault and implementing the needed corrective actions that uses OSPF features and does no change the current area assignments. You will know that you have corrected the fault when R4′s loopback address (FEC0:4:4) can be seen in the routing table of R1.

Special Note: To gain the maximum number of points you must remove all incorrect or unneeded configuration statements related to this issue.
Answer and Explanation:
To troubleshoot the problem, first issue the show running-config on all of 4 routers. Pay more attention to the outputs of routers R2 and R3
The output of the “show running-config” command of R2:

The output of the “show running-config” command of R3:

We knew that all areas in an Open Shortest Path First (OSPF) autonomous system must be physically connected to the backbone area (Area 0). In some cases, where this is not possible,we can use a virtual link to connect to the backbone through a non-backbone area. The area through which you configure the virtual link is known as a transit area. In this case, the area 11 will become the transit area. Therefore, routers R2 and R3 must be configured with the area area-id virtual-link neighbor-router-id command.
+ Configure virtual link on R2 (from the first output above, we learned that the OSPF process ID of R2 is 1):
R2>enable
R2#configure terminal
R2(config)#ipv6 router ospf 1
R2(config-rtr)#area 11 virtual-link 3.3.3.3
(Notice that we have to use neighbor router-id 3.3.3.3, not R2′s router-id 2.2.2.2)
+ Configure virtual link on R3 (from the second output above, we learned that the OSPF process ID of R3 is 1 and we have to disable the wrong configuration of “area 54 virtual-link 4.4.4.4″):
R3>enable
R3#configure terminal
R3(config)#ipv6 router ospf 1
R3(config-rtr)#no area 54 virtual-link 4.4.4.4
R3(config-rtr)#area 11 virtual-link 2.2.2.2
We should check the configuration on R4:
R4>enable
R4#show running-config
You will see a wrongly configured virtual-link command. To get full mark we have to disable this command:
R4#configure terminal
R4(config)#ipv6 router ospf 1
R4(config-rtr)#no area 54 virtual-link 3.3.3.3
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
The copying running-config startup-config command will not work but don’t worry, just skip it.
Notice: If you issue the command “show running-config” on R1, you will see these two lines:
passive-interface default
no passive-interface fa0/0 (fa0/0 is the interface connecting with R2)
These two lines make all the interfaces of R1 become passive interfaces except interface fa0/0. They are correctly configured so don’t try to disable them.

thanks for the batman when i added these extra configuration i got the the route FECO:4::4 in the routing table of R1
the extra config is :
R1(config)# Interface Loopback0
R1(config-if)# ipv6 ospf 1 area 0
R4(config)# Interface Loopback0
R4(config-if)# ipv6 ospf 1 area 54
hi could any one answering me!! i was practicing with this IPV6 OSPF Virtual Link Sim but when i remove the area 54 from R4, the output in R1 does not include any FECO:4::4
and when i leave it it show’s FECO:4::4 in R1 output. what should i do in my real exam.. hurry please >my exam is tomorrow..i am motasem
@ !: i just did the lab.. here is my results after creating the IPV6 virtual link and removing the line from R4:
R1#sh ipv6 route
….
LC FEC0:1::1/128 [0/0]
via ::, Loopback0
O FEC0:2::2/128 [110/1]
via FE80::CE02:1AFF:FE50:10, FastEthernet0/0
OI FEC0:3::3/128 [110/65]
via FE80::CE02:1AFF:FE50:10, FastEthernet0/0
OI FEC0:4::4/128 [110/66]
via FE80::CE02:1AFF:FE50:10, FastEthernet0/0
then doing:
R1#ping ipv6 FEC0:4::4
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to FEC0:4::4, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 52/61/76 ms
R1#
If u don’t see it, you must have setup your virtual link incorrectly.
ccnp_hopeful
i type every thing correctly just like the commands above and here is the result i get
L FE80::/10 [0/0]
via ::, Null0
C FEC0::/28 [0/0]
via ::, Loopback0
L FEC0:1::1/128 [0/0]
via ::, Loopback0
OI FEC0:2::2/128 [110/1]
via FE80::C202:18FF:FE30:0, FastEthernet0/0
OI FEC0:3::3/128 [110/65]
via FE80::C202:18FF:FE30:0, FastEthernet0/0
L FF00::/8 [0/0]
via ::, Null0
that’t after removing the area 54 from R4.
and also before i remove it the ping was not working.. i did that on GNS3
and my result before removing area 54 from R4 was like this..
L FE80::/10 [0/0]
via ::, Null0
C FEC0::/28 [0/0]
via ::, Loopback0
L FEC0:1::1/128 [0/0]
via ::, Loopback0
OI FEC0:2::2/128 [110/1]
via FE80::C202:18FF:FE30:0, FastEthernet0/0
OI FEC0:3::3/128 [110/65]
via FE80::C202:18FF:FE30:0, FastEthernet0/0
OI FEC0:4::4/128 [110/66]
via FE80::C202:18FF:FE30:0, FastEthernet0/0
L FF00::/8 [0/0]
via ::, Null0
so what is the problem that i have…. thank’s motasem
@motasem/! did you do this before removing the lines from R4:
R2#sh run | s ipv6 router
ipv6 router ospf 1
router-id 2.2.2.2
log-adjacency-changes
area 11 virtual-link 3.3.3.3
R3#sh run | s ipv6 router
ipv6 router ospf 1
router-id 3.3.3.3
log-adjacency-changes
area 11 virtual-link 2.2.2.2
then after you remove the lines from R4, going to R1 yields:
R1#sh ipv6 route | b FEC0:4
OI FEC0:4::4/128 [110/66]
via FE80::CE02:11FF:FE84:10, FastEthernet0/0
L FF00::/8 [0/0]
via ::, Null0
then doing:
R1#ping ipv6 FEC0:4::4
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to FEC0:4::4, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 52/61/72 ms
ccnp_hope
yes every thing done like that. and hi i tried to ping ipv6 FEC0:3::3 and it’s not coming also!
Thanks to this site, scored 1000 over 1000.
I received this sim on the exam
Hi All,
I am planning to give route exam this month..i tried downloading GNS3 labs from this link http://cisco-revision.com/wp-content/uploads/2010/12/ipv6_ospf_gns3.zip..but its showing as the domain is expired.Can someone please share the link or send it to nikamankita@hotmail.com .?
Thanks ..
Exactly same lab in exam.
I passed exam with 100% marks. There were a few new questions e.g. EIGRP authentication (key-chain authentication —> Ans: R1 can communicated R2 and R3) and RIP passive interface —-> Ans: Router RIP; Passive interface f0/0; neighbor .
All Lab questions were from http://www.digitaltut.com/.
Thanks to all who contributed in these websites!!! :)
I Passed yesterday with score 965 , thanks guys and digitaltut :) all labs from here

besides, i realised that ping from R1 to R2 fails. But, R2 to R4 is successful.
I had the same problem but when i added the following config it works
R1 config :
R1(config)#interface loopback 0
R1(config-if)#ipv6 ospf 1 area 0
R4 config:
R4(config)#interface loopback 0
R4(config-if)#ipv6 ospf 1 area 54
R4(config-if)#exit
R4(config)#ipv6 router ospf 1
R4(config-router)#no area 54 virtual-link 4.4.4.4
I hope it helps you…Good luck
@junior – It’s odd how it works for some people and not for others.. somehting must be different, but from what i see in the configs, it’s the same. *shrug*
just passed with 976. tnx digitaltut and all
Thanks….to digitaltul Today i cleard ma exam with 950marks…. lab is same and area is diffrent so dnt wrry jst read command carefully….

what does it mean? I thought for every Lab we can get total score of it or nothing! for example if the lab has score of 80, can we get 40?
to all of you who cant ping the loopback on R4:
verify if the loopback interface on R1 is advertised with ospf. If it isnt then router R4 doesnt know a route back to R1 and the ping fail.
The ping from R1 is sourced with the loopback address because the FastEthernet interface have only a Link-Local ipv6 address.
We all know that ospf rule is that every router should have logical or physical interface/link to area 0 unless otherwise it is stub.In case above router 4 is not stub .I think we need virtual link established to area 0 using
area 54 virtual-link 3.3.3.3 and then i donot understand where will the otherside will be ? any answers will help understanding the concept,
@Deep
you don’t need the other side to configure the virtual link becuase it is only applicable on the spoke routers and or the ABRs in other word…no the problem with this lab was that the loback interfaces were nto configured to use any area…and as jerry mentioned the right configs to fix this it works like charm and you still able to ping the end lobacks.
i pass 965 scores yestoday, 4 labs:EIGRP OSPF Redistribution- Policy Based Routing -OSPF -IPv6 OSPF Virtual Link,no OSPF Hotspot question
Passed today with 965/1000 , all simulation are from digitaltut exactly , still REV7 is tottaly valid 100 % .. 2 new question MCQ , simulations are OSF,IPV6,Redistribution ,PBR .
Thanks to digitaltut and all of you those who posted comments here….
Really its great site……cheers…
Can someone tell me , in the real exam also are we not able to ping R4 from R1? if we cant ping what is the reson?

Please can sombody explain to me if u have to advertised the loopback interface of the routers so u can ping them
I ran to the same problem … could not see loopback of R4.. and could not ping it .. I added this config
R1(config)# Interface Loopback0
R1(config-if)# ipv6 ospf 1 area 0
R4(config)# Interface Loopback0
R4(config-if)# ipv6 ospf 1 area 54
now I can see the ipv6 of R4 on the routing table of R1 and I can ping Ipv6 of R4 from R1
Is this something that we need to add on the routers to get the 100%
Thanks
Passed today with 976 …
Exactly the same concept even the same areas and IPs
i think the configuration is not completed. you have to advertise both loopbacks r1 and r4 to get ping working!
Thanks to Digitaltut. I passed my ccnp route with 925 the day b4 yesterday (16/11). The labs were the same but few changes in IP adds, router names/locations. For those that are yet to take, this is d right site for u. Pls understand and concentrate on the given parameters.
For this particular lab, everything was d same except they alternated d positions of Area 0 and Area 54. Good-luck.
You need to add the following commands
R1(config)#Interface Loopback0
R1(config-if)#ipv6 ospf 1 area 0
R4(config)#Interface Loopback0
R4(config-if)#ipv6 ospf 1 area 54
to ping the Loopback addresses
thnaks future ccnp
Thanks guys,
You people done marvelous job….
I just found out a new way to do this.
All i did was create two virtual-links.
One was from R2 to R3 since R2 is linked to the bone bone(area 0).
Since R3 now has a link to area 0 due to the virtual-link created from R2 to R3. then i created another virtual link from R3 to R4.
With that i was able to see the loopback address of R4 from in R1 route.

I haven’t seen anyone try that yet. To the gurus out there, you can verify this.
NB: am Mayor incase you wanna make reference to my solution. I noticed i didn’t put a name in my last post.
Wrote ROUTE today…sim in exam…excatly as is….
hey guys i will be writing the CCNP-Route exam soon and i have a question
what i’ve noticed while im practicing this sim that when i configured R2 & R3 with the virtual link without removing the command ” area 54 virtual-link 4.4.4.4″ on R4 i can see the loopback address of R4 in routing table of R1
here is the interesting part , when i removed the false “no area 54 virtual-link 4.4.4.4″ from R4, i couldnt see the loopback address.
until i added :
R1(config)#Interface Loopback0
R1(config-if)#ipv6 ospf 1 area 0
R4(config)#Interface Loopback0
R4(config-if)#ipv6 ospf 1 area 54
my question is, should i remove the false command which makes the R4 loopback address disappear? or should i leave it as it is as long as it gets the objective done?
i appreciate the feed back
best regards
I took my exam yesterday… passed my exam…trololololol….same lab simulations….7 new questions from dumps…. o.O …. ty digitaltut and the person who has provided test lab sims…. ty all :D :D
i passed routing exam yesterday and this topology is exactly
can somebody
Please, share me latest dump …. blikvi@gmail.com
HI all i will write exam tomorrow who passed the exam please tell me that how many labs are there in exam 4 or 5 please.
Please is the latest development in ccnp routing exams
http://www.4shared.com/office/J1iP8WU_/642-902.html
do we need to enter the below command in the real exam?
R1(config)# Interface Loopback0
R1(config-if)# ipv6 ospf 1 area 0
R4(config)# Interface Loopback0
R4(config-if)# ipv6 ospf 1 area 54
the above command is needed for you to be able to ping FEC0:4::4
Friends, how many hotspots are in the exam ? and could anyone share it ?
Thank you in advance
Do we need these commands
R1(config)# Interface Loopback0
R1(config-if)# ipv6 ospf 1 area 0
R4(config)# Interface Loopback0
R4(config-if)# ipv6 ospf 1 area 54
otherwise R1 will not see R4′s Loopback and vice versa
Anybody who took the test recently please answer. The GNS3 Sim seems to need this config
THANK YOU SHAHID to share me latest dump, i passed yesterday i used dumps nonentity.338q.vce or actual test v 6.2 all questions from those dumps those are 100% valid and sims are from digitultut.com same sims only ip address and are change,4 sims ( Eigpr and ospf redistribute / ospf stub / ipv6 virtual-link / pbr ) and read question carefully.
latest dumps actual test v 6.2 link http://www.4shared.com/office/J1iP8WU_/642-902.html .
I tried commands below in real exam but still failed to ping FEC0:4::4 from R1 though i finished it with FEC0:4::4 showing from R1#show ipv6 route
R1(config)# Interface Loopback0
R1(config-if)# ipv6 ospf 1 area 0
R4(config)# Interface Loopback0
R4(config-if)# ipv6 ospf 1 area 54
@g-shock, You tried to ping but it didn’t go through? Strange, being that you saw it in the routing table.
Using the gns lab for this sim, I finally see FECO:4::4 in R1′s routing table. However, I am unable to ping it. Am I trying to ping incorrectly? ping ipv6 FECO:4::4/128 or how do I ping it?
Please reply.
PS. We MUST advertise the loopbacks in order to see R4′s LO in R1′s routing table!!!!!!!!
R1(config)# Interface Loopback0
R1(config-if)# ipv6 ospf 1 area 0
R4(config)# Interface Loopback0
R4(config-if)# ipv6 ospf 1 area 54
@dabba
try ping FECO:4::4
and it is gonna ask about outgoing interface type FastEthernet0/0
its gonna eork
Dear all,
I will take CCNP exam on 18th january 2012
please I need update on the latest questions.
Thanks
For all you all having problem, of course you will be able to see R4 in routing table because its there on the table but when you ping R4 will see it but unbale to respond due to it doesn’t know where to send it. Same senario from pingin R1 from R4. To fix this you have to add this command in R4
area 54 virtual-link 3.3.3.3
From R1
area 0 virtual-link 2.2.2.2
after that and youre all good. Let me know what you guys think.
@Dabba
To ping just simply use this command
ping fec0:4::4
good luck
thanks maggie and bunso. it doesn’t work tho…gotta figure out why
@dabba
just follow the official instruction above and do the same for R1 to point virtual-link to R2. Then on R4 point it to Virtual-link R3 in these way when router receive a ping, it know where to send it back. Without those to config in R1 & R4 router it will receive the ping then drop it.
Here is the command from R1
enable
configure terminal
ipv6 router ospf 1
area 0 virtual-link 2.2.2.2
FYI if there is a virtual link already in R1 you have to use the “no area # virtual-link #.#.#.#
for R4 command;
enable
configure terminal
ipv6 router ospf 1
area 54 virtual-link 3.3.3.3
FYI same scenario if there’s already virtual link in R4 you have to remove it and put the configuration i wrote above.
good luck
In the exam, the loopbacks were already advertizing. I didn’t have to config that. Ping worked perfectly in exam. I did not have any other goofy issues mentioned here. Topology was exactly the same as above.
Can someone send me GNS3 LAB file for it ???
the one that i have looks same but, configured as different and when i typed sh run command,
it comes up with different result,
thanks yemasin@hotmail.com
Thanks @Anon for clearing if needed to config more. I do not know why some people are suggesting goofy configs such as having to config between R1 n R2 a virtual link. The question I had was CCIER&Sbound configuration is not complete, that is why R4′s loopback is not advertised to R1 and vice versa. Sorry if I offended somebody.
@me Actually they are not goofy config, they are actually usable to learn and find out if does really work. If you read the entire thread people are asking why they can’t ping and we just provided them how to make ping works. Learning something new is a plus than just trying to pass the exam.
On the other half I agree with you we need to focus on the question if it doesn’t ask you to make extra config then don’t do it.
As the question say. ” You will know that you have corrected the fault when R4′s loopback address (FEC0:4:4) can be seen in the routing table of R1.”
Again to everyone focus on the question, and only give them what they ask.
Good luck to everyone
On the real exam, is lookpback address already configured ?? do i jus follow that configuration??
so what configuration exactly do we put in the exam??
do we have to configure lookpback 0 address as ospf 1 on R1? or is it for GNS3 prac only??
thanks
Hello Friends,
I just started to study the ROUTE test after taking almost two years off from passing the CCNA. I am planning to take the ROUTE test in two months. Are the Sims, Drag and Drop, Questions, and everything else on this site still valid for the ROUTE test?
Thank you all!
Anyone please verify this output please?..
R1#sh ipv6 route

This output i got from the GNS3 lab. I cant ping the router from R1 to R4. So please anybody point out my mistake and please give me the solution for this lab.
@ Eager
Making ping work is not necessary as the Question say
” You will know that you have corrected the fault when R4′s loopback address (FEC0:4:4) can be seen in the routing table of R1.”
In your output you still dont have R4 shown in R1 so that will be wrong to correct it go to R4 and run (sh run) and verify if the virtual is pointing to 3.3.3.3 and make sure the area is in 54.
If not you have to delete that in the config and replace it with this
area 54 virtual-link 3.3.3.3
And that will enable R1 to see R4
If you want ping to work just add this command to R1
Area 0 virtual-link 2.2.2.2 Ping should work but again the test didn’t asked to make ping work.
Goodluck
@Jelooos
the configuration that Digitaltut provide us is accurate and correct. Just make sure that you run (sh run) in all routers and check for virtual link config and their area.
Goodluck
@bunso
ya u r right. I got the output after adding the below functions in R1 & R4 router’s. Also now am able to ping from R1 to R4.
R1 config :
R1(config)#interface loopback 0
R1(config-if)#ipv6 ospf 1 area 0
R4 config:
R4(config)#interface loopback 0
R4(config-if)#ipv6 ospf 1 area 54
Thanks Bunso……………..
Only one virtual link is necessary, the one through area 11.
just passed 906. Got 4 labs. Make sure you go through the mixed questions of pass4sure 300Q. All the best guys, will someone please point me to the TSHOOT site?
DAN:
Can you share your experience on exam? sims? what were the topics that appeared most?
I have the exam in next week and thanks for the support.
Site for TSHOOT:http://www.networktut.com/
Thanks
passed today with 953, same sim as mentioned above.
copy run start will not work , dont panic thanx diditaltut.
I Wash This SIM Still Valid
My Exam In 1/2/2012
I passed the exam yesterday :-) and this lab was appeared on the exam :-)
