CCNP TSHOOT Troubleshooting 1

125 Comments

1. Rene,I think u forgot to share The Topology & Configs .

2. i cannot find the configs for GNS3 either. Is this working for anyone out there ?

3. Yup, likewise here. I can’t find any attached topology file or config file. thanks,

4. Oh, I have been waiting for this!!! I’m sure since you just posted, that the things people are talking about are coming soon. This is great!!

   Looking forward.

   You know, I really don’t have a life, I just hang out here waiting for labs! Ha ha.

   1. The attachments are now here, I forgot to publish them (oops!). I think this lab will be great for learning how to troubleshoot. It’s more difficult than what you’ll have to do on the CCNP TSHOOT exam.

5. It is not working "Dynamips error" connection lost
   I used for – c3725-adventerprisek9-mz.124-12 .

6. hi rene
   after editing file topology.net, i got error "invalid destination interface"

   pl suggest me

   thanks

7. the topology is not opening in gns 3 please help………

8. This lab was AWESOME!!!!!!
   Again I almost gave up not using show run!…. well… I have to admit that I took a little look on DSW1 to figure out about the static mac address ;P (I totally missed that one!) but besides that I solved it fair and square 🙂

   I almost missed BGP on this one, I was going to create a default route to ISP until I looked at BGP as a routing protocol on R1!

   I loved the frame-relay mess! ipv4 and 6! that was a challenge! (Daisy-chain DLCIs, who on earth would ever do that!? hahahahahaha)

   Thank you Rene, this was an incredible lab! I spent some time on it! I really feel more confident on getting my TSHOOT Cert.

   Keep up the good work!

9. Rene is it legal to download the quick reference guide?

   1. Hi Orla,

      Sure why not? Cisco offers it as a PDF file.

      Rene

10. Rene thanks a lot for these wonderful Labs, they are really helpful and they also test your networking understanding…..thanks once more.

    1. You are very welcome!

11. Thanks RENE, but it does not works on GNS3 windows, I’ve tried c3725-adventerprisek9-mz.124-12.bin.

    any suggestions?

    1. What error are you getting?

12. [color=gray]Thanks RENE, but it does not works on GNS3 windows, I’ve tried c3725-adventerprisek9-mz.124-12.bin.

    any suggestions?[/color]

    you have to edit the network file and place the rigth path for the working directory and the IOS directory, after you fix that it’ll work on windows 😉

    Good luck!

    1. Guys, I`m using the propper path and c3725-adventerprisek9-mz.124-12.bin which runs fine apart from this lab and I get this:
       error:
       *** Warning: Connecting DSW2 f1/4 to DSW1 f1/4 resulted in:

       Reset error, lost communication with hypervisor?

       Please help!!!

13. Hi Rene,
    I start the final config, but the client can’t get the IP address from the DHCP server. It’s really strange for me. I can’t find the solution to fix it. I made the PART (you know why part) of this lab on Packet tracer and it’s working. Could you please check or explain why the client’can’t get the IP address.

    Thank you

    1. I could but there are many components in between that could cause the issue. What did you verify / exclude what the problem could be? You can also take a look at the sample of my TSHOOT book. You can read the chapter where I walk through the troubleshooting of this lab for free.

14. Thanks JeramelF

    Its works now 😀

15. I have opened this lab up a number of times. I have a MacBook Pro, and all the labs on gns3vault have worked. Now, this lab doesn’t open. Here is what I get: [URL=http://www.4shared.com/photo/xICHsVmx/Screen_Shot_2012-09-26_at_9363.html][IMG]http://dc590.4shared.com/img/xICHsVmx/0.9699126212460374/Screen_Shot_2012-09-26_at_9363.png[/IMG][/URL]

    Then I get the “connection lost” message and the topology doesn’t start. Any help would be great. Thanks.

    1. HI rdm1860, I had the same problem and fix it when add the
       sparsemem = True for all routers.
       Please check .

       1. Not sure I follow, is that in the topology.net ?
          And, I am assuming that you are aware that I am doing this on a Mac.

          Thanks for clarifying.

       2. I added that line to my topology, see below comment where I subsequently added AFTER the idlepc value, on next line.

          I now just get "connection lost".

          This must be a hypervisor issue, but I cannot figure it out.

          1. So Rene was right again! I had duplicate aux ports int the topology.net file. Much better to run on gns3 for Mac than on gns3 for windows INSIDE vmware fusion!

16. The lab has worked fine( only some edits are required in the .net file). Rene you are really a great guy. Now I am pretty confident that I will be able to nail down the CCNP THOOT EXAM in near future. Rene, thanks a lot for these superb labs.

    1. I’m using a mac. What edits would be recommended? I have never had to edit any other lab. This is the first that I have had issues with.
       I edited the topology.net. I now am getting an error in the console as follows. below the console error, I will show my corrections to the “.net” file. This is the only lab I have issues with.

18. Thanks, it was the aux ports, as you said.

19. couple of comments. Everything on this lab is great!

    1. It’d be fun to add the topo again with new problem tickets.
    2. GNS3 doesn’t play with vlans well, or vtp so one has to use the vlan database to adjust that.
    3.The L3 topology is mis-labeled between DSW1/DSW2 and R4.
    should be 10.1.4.4 and 10.1.4.8 /30 respectively.

    Taking TSHOOT Monday.

20. It"s my pleasure.Wish you all the best.

21. Good stuff. Love it!

22. I am running 0.7.4 Mac OS X 10.8.2 and am trying to bring up the tshoot topology.net. I am using a 3745 model with the following IOS image – C3745-advipservices9-mz.124-25c.bin. I am getting the
    message – Could not connect to server. Is the mixture of OS and
    software correct?

    1. You are going to have do some edits in textedit to the.net file. If you read my issues above, I had similar problems. I edited the aux ports to be different ports for each instance. There are other issues that you may need to address like the length of the file paths, no spaces in the paths.

       I’m assuming that you uncompressed the file like with other labs?

       Also, read online, once you get it going, that there are special ways of addressing the switching commands on GNS3.

       Good luck, once I got it to work on my Mac, I made excellent progress.

23. Please advise on these errors trying to start the lab and unable to resolve this on my own..

    1. Hello,

       I have read all the other comments and all aux ports do in fact have different numbers, but I am still getting the aux port already in use error. Any ideas?

24. where can i find the tickets for the tshoot exam with complete questions?

    1. It’s been a while since I read the comments on this lab. It seems that the MAC has something running on the ports that GNS3 uses for AUX. You can change these. I also recommend to use the C3725 router and not the C3745, this might cause issues.

       In the future I’ll add more labs like this one, with new tickets to troublshoot.

25. Thanks Rene – these labs are just what i was looking for. Tshoot is a funny exam to prep for as you really need broken labs to start with, not build them fro scratch like you do for route & switch.
    I was having the same problems with the ios not being found then the aux ports not working. The advice here worked for me, i changed the path in the .net file for the IOS then had to change the values for the duplicated aux port no’s. Now i got it working in windows i may try and get it going in Linux as well as windows does not run GNS as well as Linux IMO

    1. You are welcome. Linux shouldn’t be a problem as I built these labs using Ubuntu.

26. Dear Brother i am having a problem in loading the GNS3 IOS file you have mentioned. it is giving this error

    Local IOS image/Data/GNS3/IOS/C3725-AD.BIN
    cannot be found for hypervisor 127.0.0.1:7202

    then in the end it asks for alternative image:
    even if i will select alternative image it does not work
    please help

28. Hi,

    Cool lab. It was a pleasure to solve it. Many thanks.

29. how can i load the configs to Gns3? i am new to gns3 and trying to figure out how to do that. i can load the topology on there but no configs …

30. i cant see to console to DSW1 and DSW2

31. Hi Rene,

    Now i’m CCNP.
    Thanks for your TSHOOT book and this site.

32. First off thanks for the time and dedication to creating/updating this website, it’s truly appreciated.

    quick question, I only noticed now, lol, that you have NAT at the top i’m gessing for internet access somehow you wanted us to nat 192.168.x.x to the 209.65.200.225, not sure, but i just leaked a default route to the rest of the network incluing vlan10 on the switches below and this solved my problem (with the exception of adding default information originate to the ospf routers and a null0 route in R1) I also had to force ospf in R4 to redistribute matching external and internal routes. I’m not sure if this is what you wanted, but it works. Only downside is that the ISP knows all the lan routes including my switches vlan interfaces, which is usually not optimal. lol..

    thoughts?

    1. You have done great work here. One thing though. What are these static mac addresses that are added to DSW1 and DSW2 configs. Where do they come from and why are they needed? Can the switches not learn them dynamically.

33. In attempting to solve ticket 1, I got lost and after hours, paused to ask what I was doing. I guess I am trying to say it’s easy to get lost into it. Closed everything, and I am going to have another go.

34. Got it! Ticket 1 that is. Decided to do a separate DHCP troubleshooting lab on this site too, when I figured that one out, I was able to solve this one. Well seems i fixed ticket 2 while at it 🙂

35. Pls advise as i get an error message when i try to load the topology. i have loaded the same IOS image and still no luck. If there is anything i can change please let me know what to do to get it working

36. Hi Rene,

    Its not working for me…below is the error.

    Reset error, lost communication with hypervisor?

    1. the error is shown to you right at the bottom.

       [b][i]*** Warning: received dynamips server error:
       aux port 2100 is already in use
       *** Warning: received dynamips server error:
       aux port 2101 is already in use[/i][/b]

       If you open the topology.net file in notepad (or notepad++) (my favorite), do a search and replace for:
       aux = 210

       there is this line for every device in the config but for whatever reason the original file has the same aux port number on at least 2 devices and this config has 15 devices.

       what you need to do is search the file and starting from the top change all of them so the numbers are sequential

       aux = 2100
       aux = 2101
       aux = 2102
       and so on until you change all of them. should only be 15 of them to change.

       then open the GNS3 app and click on EDIT>>PREFERENCES and click on Dynamips to left of window. look for the BASE AUX PORT: and change it to start at 2100 TCP. default in windows looks like 2501. Or you can leave this alone and change the numbers in the topology.net file and start the port numbers from 2501 down the line for all devices.

       any c3725-adventerprisek9-mz.124 ios image should work but try to use the highest ios version you can find. I am using c3725-adventerprisek9-mz.124-25d.bin

       Once you have your ios setup in GNS3, place 2 c3700 routers on a blank page and connect them via serial and start them. click CTRL-SHIFT-ESC to open up the windows task manager so you can monitor performance as you now have to set the IDLE PC value. Once you get that done and your cpu drops to 0 or very near it then you are good to go.

       Note1: It looks like he created this topology under Linux O/S or similar as you will notice in the .net file all the paths have a forward slash /.
       No need to change anything here because GNS3 recognizes the change and modifies the file. Once you successfully open the lab topology and save it, if you reopen the topology.net file you will see all the paths changed to whats on your PC.

       Note2: apart from this issue, I find that changing the "working directory for dynamips" helps.
       change it to C:\GNS3_TEMP

       click the TEST SETTINGS when you have made your changes. APPLY>>OK.

       Open up the topology from the lab here and everything should be smooth sailing… hope this helps.

37. [b]I start gns3 topology and at start it gives me connection lost error
    ………………..I have read All comments and applied all Things but still scratching my head .[/b]

    Sir rene Plz help me out

38. Rene sir,

    Please help tried everything but not working…u can share the topology JPG image with the ip addressing will get the topology build and then import the configs for them..

    Regards,
    Arun

39. Hey Guys, I managed to get the lab working, i used the IOS image below, not sure where you guys can download it as it was given to me by a friend. Try googling it, it works:

    c3725-adventerprisek9-mz.124-15.T14.extracted

    Good luck

40. Hi rene,

    Today somehow managed to built the topology by my own taken 2 platform of routers…2691 and 3725 and built it with same config as urs..seems solved the DHCP part of it…working on 2nd ticket…

    thanks

41. finished solving this topology…took me 3 days…mainly becoz of my laptop RAM …can not handle 13/14 devices at a time….Anyways it was gud..tx rene…

42. If some of y’all are still having problems getting the files to work then I suggest checking out this post by Rene:

    http://gns3vault.com/Faq/203-bad-number-of-parameters-1-with-minmax22.html

    He even has a video at the end.

    Thanks Rene for taking the time to create this lab (and all of the others)! I did all my ccnp switching using two 2950s and two 3550s – so it’s a little weird navigating through the c3725’s IOS set as the four switches. I could rewrite the configs and use my real switches but then I’d probably spot the problems real quick defeating the purpose of this lab (i.e. don’t use “show run”). 🙁

    But thanks again for taking the time to set these labs up! Cheers!

43. any chance of a screenshot of how the FR switch is set up?

44. help pls, i’m experiencing issues loading the lab, getting connection lost, when trying to load the .net file, any clues pls ?

45. Thank you very much for the great lab Rene.
    But i am facing issue where clients 1 and 2 are not getting ip addresses from DHCP server . I saw similar comments from Polinoma .

    Rene and Polinoma
    Can you please help me rectifying this issue .

46. I’m having the same issues like others with Client 1 & 2 not getting an IP address even after loading the Final Config files.

    It’s a shame as it is a grate lab. I practice the TShoot lab on my real hardware lab but like to have the option of doing the lab while on the road.

47. Thanks a lot for Renne These wonderful information, thanks to you now I am CCNP R & S. Once More ….guys do not hesitate to buy the material is paper gold Renne…

    [b]I studied from Renne books for all exams…[/b]

48. If you experience issues with the topology esp with aux ports try using ravi p sharma’s topology.

    After spending 4 days, without reading all the comments above, I finally used that and it worked perfectly!! If only I had seen it earlier!!!!

    Would also like to add used 3725, it just makes everything so much more simple.

49. have you the video solution pls?

50. Hi everyone!

    any progress on how to solve the issue with importing lab into gns3? I gave up, it could only work if you have exact same physical topology with matching interfaces. Hey, Rene, why don’t you publish the topo image with interfaces shown so that first we can build the right topology and load the equipment with config files.

51. I tried the netbrain to build the topology, but you’re obviously using some tricks to make incorrect so to speak, so netbrain produces some odd output.

    Please put the interface id you’re using in your lab

    thanks

52. Thank you very much for your great labs and book.
    Today i passed the exam with 1000/1000.

53. Hi Guys

    Does anyone have any ideas about how to solve the "lost connection error". I am tying to open the lab on windows 7 and I keep getting this error. I have downloaded the c3725 image Rene instructed we should download but it does not open. Any help.

54. can anyone answers these questions?

    1. What did we create vlan 200.
    2. why didn’t we create vlan 10 and 20 on ASW1 and ASW2 ?
    3. Do we need to provide IP addresses on Vlan 10 and 20 on ASW1 and ASW2?
    4. Do we need to configure EIGRP on ASW1and ASW2 switches?

    I think the diagram is not clear, it should be.

    Kindly help.

55. I am unable to load this topology in GNS3. Getting connection lost error. Please help

56. – did you setup the image in gns3 first?
    -please post all the steps you did in gns3 to try and make this config work..
    -what O/S are you using?
    -if possible, take screenshots of your gns3 setup so we can see how you have it setup. without enough information, it is hard to give help.

    you also need to take a look at the console in gns3, the bottom part of gns3, and copy and paste all the errors that are in there to this site so we can all see whats going on.

    There are errors in the original topology.net file. Here is a link to replace the one you downloaded with the one I fixed.
    Just delete and replace with this one. Then as long as you have a c3725 image setup in gns3 it should work. Dont forget to setup IDLE-PC !!! Just start about 3 or 4 routers and wait a minute or two then do the idle-pc.

    The only errors in the topology.net file are duplicate entries for aux = 2xxx

    no need to change any other lines. this is because as long as you have the image setup in gns3 and everything else in gns3 is working, then once you open the topology and SAVE, gns3 makes the changes in the file according to what settings you have setup in the gns3 program itself. so, just download the fixed file below..

    Click [url=https://dl.dropboxusercontent.com/s/lnk44xyj4cag0mx/topology.net?token_hash=AAHYbCi_XLJWCbFljnltojL3sK9eHum_d1UO9Hl-qZ7IhA&dl=1]here[/url] to download.

    Once you replace the topology.net file and try to start it for the first time, it will ask you which image to use. Just select the one you saved and after it loads up, save topology in gns3. Thats it !!

    1. Thank you very much pcdocta !

       your suggestion helped me ,,,,

       Regards

57. After a little bit of hair pulling I finally managed to get this lab up with no errors in gns3. After looking at ticket 1 and trouble shooting it for an hour or so I finally broke down and cheated and looked at Rene’s answer in the TSHOOT book. Well I had already done what was suggested there and it still wasn’t working. I’m noticing a few odd things though on DSW1. I’m not used to looking at an ether switch module slotted in a router so I’m not sure if this is normal behavior or not. I noticed when I do a show ip int bri on this device it says all the vlan interfaces are up but the line protocol is down. So when you try to do a show standby to troubleshoot the next ticket it tells you hrsp is stuck in the init state because the interfaces are down.

    Also, when looking at device ASW1 I’m assuming that workstations 1 and 2 are plugged into ports f1/4 and f1/5 since the other active ports are used for etherchannels. When I do a show vlan-switch on this device it only shows the default vlans…no vlan 10, 20 or 200. I discovered this when I noticed int f1/4 was in vlan 200 instead of vlan 10 where it should be for the workstation. I thought maybe this was why i wasn’t getting a dhcp address so i had tried to move it to vlan 10 and was informed there was no vlan 10. Anyone else seen this or do i have something incredibly pooched here?

    1. I have the same problem, all SVIs are up/down, no vlans on switches and i can’t even add them . This lab is useless for me…

    2. Hi

       The reason why the vlan interface shows down is that fact that with ether module the vlans get saved in a file "vlan.dat" When you load the topology you need to recreate the vlans.

       The interface vlan is there but no Layer 2 vlan exist. You need the add them from Privilege mode:

       DSW1#vlan database
       DSW1(vlan)#vlan 10 name CLIENTS
       DSW1(vlan)#vlan 20 name SERVERS
       DSW1(vlan)#vlan 200 name MANAGE
       DSW1(vlan)# exit (NB)

       Do this on all switches…

58. hi Rene ,

    I am unable to run this topology on my system ,,,, I have the same ios running in gns3 ,, but at the end it does not upload the topology and gives the error of connection lost ,,,, please help ,,,
    Regards

59. I cannot open zip file on my computer.

60. I have same problem as avesimasud above. Its a shame cant get it working as site looks great and would help me finish my CCNP. As I am not the only person experiencing these problems would it be possible to get any definitive advice on how to load the topology into GNS3?

    1. if you only bother to READ THE POSTS ABOVE you will see that even avesimasud said thank you that he was able get it working. READ READ READ THE EFFIN POSTS and stop being lazy

61. PCDOCTA my apologies for being so hasty in my comment. I was in panic mode as I found Tshoot very different from switch and route. Glad to say it is working now having downloaded your modified network file and many thanks for your interest and help to people here..appreciated. Jezza in Dublin

62. [b][/b]I already have the solution for problem with Hyperversor error.

    You should change:
    Image
    Aux: 2001-2012 in your topology and Remember change it in Preference/Dynamips too.

65. where is the lab download?

66. Hi all

    I am a bit stuck on the 3rd ticket. There is no default route to the BGP network from ospf. I can do a redistribute bgp (I dont think this is a good idea especially if you receive a lot of routes from the ISP. To redistribute all that routes might make the router slow) or using a static route with the default information cmd. There is not specified what is the company policy would like us to do.

    THANX for all your great labs, I enjoy them more that World of Warcraft 😛

67. Hi Guys,

    SVI Vlan 20 and 10 are continuously fluctuating on both DSW1 & DSW2 due to which EIGRP is also fluctuation. Is it a issue or is it due to my Core i5 PC with 4GB of RAM ?

    Also I am stuck at 2nd Ticket. Any hints ?

    Rgds,

68. Hy Guys!

    I have a problem with R1. It stops booting at this point:

    SYSTEM INIT: INSUFFICIENT MEMORY TO BOOT THE IMAGE!

    But all routers have same parameters (IOS version, memory size, NVRAM size, Disk0 size) Does anyone experienced this problem?

    P.s.: Rene, all labs are fantastic! 😉

69. I seem to have the same issue too :s… I’ll let you know in case I’ve found a solution for this issue

70. Concerning the errors received on R1 the problem can be solved by increasing the amount of memory to be used by the router from its configuration tabs.
    Other than that Rene you did a great job by creating such an amazing lab !! I admit there was some useless static routes that I got out of the way, and some frame-relay issues.
    I cannot thank you enough, you’re one hell of a Lab Professor ! 😉

71. Trying it out the lab …

72. Where on this webpage, do you find the topology to download?

73. You have to register on this site and login then you will see the topology for download.

74. I’ve been logged but I don’t see the link to the topology.

    1. I missed this one during the migration. Just uploaded the files!

       1. I see rs. Thanks!

75. Where is the PDF to download??

    1. I just added the attachment. Forgot to do this during the migration.

76. I solved this and was reviewing the final configs to see if my solutions were the same.

    They were not but I’m confident after loading the final configs, there is at least one omission.

    On R4 you have to redistribute EIGRP into OSPF or there is no route back to the clients.

    I’m still researching but I still haven’t figured out why both nssa options “default-information-originate” and “no-summary” were needed. For me one or the other worked.

    Excellent lab….much much harder than the TSHOOT exam and on the exam, you have to use SHOW RUN because debug does not work. If you you resort to SHOW RUN like I did after being frustrated for a day….it’s still harder than the Exam.

77. Hi Rene Molenaar
    Pls keep up the good work

    Without “show run” is like your hands are tied ….but its really difficult but if you do so the real life/exam would feel easy

    Are you planing to upload any video solution to all/some Tshoot Labs ?

    Regards

78. Not working withc3725.bin any alternative ios image??

    1. Pretty much anything 12.4(15)T or thereabouts. 12.4M will work for most non-MPLS, non-DMVPN Phase 3 things too.

79. Great looking lab. I can get the lab to load but if I do a show run I only see the base configs, no addressing or configuration parameters applied to the devices.

    I am running GNS3 on Windows 7.0. Do I need to do some editing?

    Thank you,

    Murrell

80. Very challenging lab, solved it 100%!

81. Just downloaded GNS3 1.2.1 and the above posted files(3) do not work with it. The error I get is,

    Server error [-3200] : Dynamips executable C:\Program Files\GNS3\dynamips doesn’t exis

    Even though dynamips is properly path’ed and a new topology works without any dynamips errors. But loading this one does(provide error).

    Mr. Molenaar, please configure the files to work with the new GNS.
    A big thank you!

82. Hey Rene

    great work. I have your 3 books on CCNP. Really well written.

83. Hey Rene. I have downloaded and run this on GNS3 version 1.2.1 There are links missing to the frame relay switch and some of the configs haven’t been done

84. It dosen’t work for GNS3 version 1.2.1. :((((

85. I get all .py file error cant find even I did edit all path for IOS and config files. can someone help.Thanks

86. now that problem is resolved but CPU goes 100% with c3725-adventerprisek9-mz.124-15.T14 this image any clue?

    1. Need to adjust idlepc.

87. i am running version gns3 1.2.3 . I am missing links and rx errors that aux con port already in use….

    1. Hey Chris,

       Could you pls advise what u have done to resolve ur connectivity issue. I am also running newer version 1.3.13 and i cant see links either.

       Thanks in advance.

88. Hey! Thanks so much Renee. This is a great lab. I rebuilt it from scratch so I would really know the ins and outs in preparation for the big exam next week (TSHOOT). As per a comment I saw on the Packet Pusher Podcast, I am going to use this lab, and have my boss or co-worker go in and break something random a few times each day, so I can tshoot it in preparation! Great stuff Renee! Thanks again.

    One note: I had trouble pinging past the ISP to the web server, even with converged BGP. I ended up adding a default route on the WebServer router pointing back at the ISP’s WebServer-facing interface. I’m still wondering if I missed something else….oh well.

89. Finally got the lab working in latest GNS3, but really stuck on ticket 1.

    -I figured out that the dhcp pool in R4 was misconfigured.
    -I had to cheat and use “show run” on DSW1 to see a bunch of static entries for MAC addresses coming from ASW1 that needed changing.
    -I figured out that ASW1 didn’t have switchport access vlan 10 associated with the interface going out to Client 1
    -HSRP group 10 between DSW1 and DSW2 did not have the same virtual gateway…made sure both were set to 10.2.1.200
    -set default-gateway on client1 to 10.2.1.200

    So far, DHCP is still not going through

    1. Ah! I got it.

       -Client1 doesn’t get a gateway since it’s broadcasting for everything, so “no default-gateway” to get that out of there.
       -Broadcasts can’t cross subnets, so DSW1 needed to be a relay. put the “ip helper-address 10.1.4.5” command on the vlan10 interface.

       DHCP is up. Man, this is a good lab.

90. R4 can only ping 226 can’t see route for 209.65.200.240/29 ,anyone come across this issue ,where could be issue ,as R3 is able to ping 209.65.200.241.please help if possible strange can’t see route for /29 but able to see /30 route for 209.65.200.224

    1. I have the same exact problem.

       Funny thing is, I could swear it was working fine up until I saved all my configs to start-up config, saved the lab, and reopened later. I’m not seeing anything in the configs between R4 and ISP nodes that could be causing this.

       I did an ip nat debug on R1 and watched R2 and R3’s addresses get translated when I ping from them, but pinging from R4, nothing shows up in NAT debug.

       This is really weird, and annoying. It’s stopping anything from the EIGRP side from getting through.

    2. sanjeevl,

       Stick this in your R4 config for now until a better explanation is found:

       ip route 209.65.200.241 255.255.255.255 209.65.200.226
       ip route 209.65.200.246 255.255.255.255 209.65.200.226

    3. sanjeevl,

       Is your area 34 on R3 and R4 set up as NSSA or TOTALLY NSSA? If its just NSSA that could be your issue. I changed mine to Totally NSSA and that fixed my issue.

91. I configured everything from scratch, i did the IPv4 Layer 2/3 Topology on Packet Tracer 6 and the Ipv6 Layer 3 on GNS3

    Issues to solve where:
    Client 1 was not in Vlan 10
    Trunks between Layer 2 and Layer 3 Switches were not allowing Vlan 10
    HSRP configuration for Virtual Gateway Address was wrong on DSW1
    DHCP Configuration-Wrong Network Address used
    EIGRP passive Interface
    Hello-Interval of 7 causing no Adjacency for ipv4 OSPF
    Wrong Access-list for NAT on R1
    BGP config btwn ISP and R1 were wrong
    The Tunnel Source was missing on the IPv6 ticket

    Gret Lab, i salute you

92. Hi Rene,

    I have this error everytime I load up the load and I can’t seem to solve it

93. I got it working with the latest GNS3 version.
    Thanks anyway 🙂

94. Is this topology still valid for this exam?
