CCNP TSHOOT GNS3 Topology

This is something I had in mind for quite some time but today I finally created the CCNP TSHOOT topology for GNS3. The topology that is used for the exam has been released by Cisco so it’s not a secret or anything. This is pretty cool because it means you can start troubleshooting the same network you will face for your exam! To save you the trouble I have rebuilt the whole topology in GNS3 which is 95% the same as the Cisco example, there are some minor differences:

  • It’s impossible to use all CCNP switching commands in GNS3. I have used the NM16-SW module so we do have trunks and portchannels. We can’t play with different trunk types (dynamic desirable, dynamic auto and such) or play with PAGP or LACP. Make sure you practice on this before you take on the exam!
  • Don’t forget if you want to see vlans on the NM16-SW modules you need to use the show vlan-switch command!
  • If you download the official Cisco PDF with the topology you will see that the interface + port channel numbers might be different. Not a big problem but something you should keep in mind.
  • I had to manually change some IPv6 link-local addresses because they were the same on all serial interfaces.
  • There are 13 routers to run so make sure your IDLEPC value is correct. I’m using the 3725 routers (because of the NM16-SW modules).

The complete topology has been preconfigured for you. All routing protocols, redistribution, vlans etc are 100% configured. This is the topology the way it is meant to be. I highly recommend you to study this topology to ensure you know what is going on and how things are connected. Download the GNS3 file and the Cisco TSHOOT Exam Topology PDF and look at them thoroughly. It’s a good idea to draw your own network diagram.

Having said that, let me explain the topology a little:

  • Client1, Client2, FTP Server and Web Server are routers with “IP routing” disabled. This turns them into hosts with a default gateway.
  • Client1 and Client2 receive their IP address through DHCP. They are in VLAN 10.
  • ASW1 and ASW2 are access layer switches with trunks (etherchannels) to DSW1 and DSW2.
  • DSW1 and DSW2 are distribution layer switches. HSRP has been configured to act as a gateway for Client1 and Client2 in VLAN 10.
  • EIGRP AS 10 has been configured on DSW1, DSW2 and R4.
  • R1,R2,R3 and R4 are running OSPF. They are connected by using frame-relay point-to-point subinterfaces. I recommend to take a look at the different DLCI numbers that are in use.
  • R4 is also the DHCP server for VLAN 10. DSW1 and DSW2 have been configured to relay DCHP discover messages.
  • R1 has been configured with BGP AS 65001 and peers with the ISP router that uses BGP AS 65002.
  • R1 has been configured for NAT so all hosts within the private ranges 10.0.0.0/8 and 192.168.0.0/16 are able to access AS 65002.
  • The ISP router advertises network 209.65.200.241 /29 through BGP to AS 65001.
  • You might notice Client1 and Client2 are unable to reach the Web Server. This is because OSPF AREA 34 is blocking the external LSAs (BGP is redistributed into OSPF on R1). I left it this way but keep it in mind.

IOS:

c3725-adventerprisek9-mz.124-12.bin

It’s a very good idea to start this topology and play around a bit. Check how and why things are working. I will be releasing new labs with troubleshooting tickets that are based on this topology very soon.

Have fun! If you have any questions please leave a comment or drop a message in the forum.

    Just donated to say thanks for the whole site but especially this lab as I just passed TSHOOT and I am now a CCNP 8)

    It was good to practice in a very similar environment to the exam and having the lab pre-setup was a great time saver – much prefer learning to messing about with basic topology!

    Now looking forward to using the many other labs to help practice for whatever the next cert I go for is or just to learn technologies. Seeing how many labs have been addded I may be some time! :o

    Thankyou so much for building this for us. I’ve used a ton of Renee’s labs as my primary study tool for certs. The port channels didn’t work out for me but easily fixed by using only one interface. Adding area 34 no-summery to R3 will fix the issue with client1 not pinging the webserver. I should be taking TSHOOT next month. So I’ll be wiping out the configs of the routers and starting the configuration over to get better familiarized with the topology.

    I’d really enjoy a few broken version of this lab for troubleshooting purposes.

    Thanks again Rene

      Yes that shouldn’t be any problem. What if you copy/paste my portchannel from the configuration and change it? Keep in mind there’s a difference between layer 2 and layer 3 etherchannels.

      You should create a new project in GNS3, click and drag 2 routers and connect them to each other. Save it and then open the topology.net file that it created in notepad. Compare it to mine and make the appropriate changes so the folder names are similar. That should work.

    Many thanks for supplying this configuration.

    I made a few changes to my topology surrounding HSRP, added tracking and decrementing commands in. I also broke down the ACL on R1 into separate sequences in order to test the permit/denys for the 10.x.x.x range. I also added loopback interfaces for R1, R2, R3, R4 :-)

    Thanks again,

      Thanks for your message Danny. I tried to re-create it to match the Cisco topology as close as possible but it’s of course great to add/change things yourself. My advice is to get very familiar with the topology and understand how everything works.

    Hi, came across this website a few days ago and i haven’t stopped wondering where i have been all the while! the resources are simply magnificent (for those of us who engage in self study). I have recently completed the CCNP route and switch exams so i’m currently preparing for the T-shoot. I have downloaded the lab topology but i seem to have a bit of an issue in using it…when i import the config into the topology, only the router configs are loaded, i do not have any joy with the ASW and DSW. i have the relevant router 3640 IOS. Kindly advise, was it designed that way or is there something i am doing wrong? I await your prompt response & pls do keep up the good work.

      Hi Wada,

      Thanks for your message. The ASW and DSW devices do have a configuration, just open the CFG files in notepad/wordpad and you’ll see it. Not sure why they don’t open but you can just copy/paste them to your routers manually?

      Keep in mind the ASW and DSW devices are routes with the NM16 switch module. They can’t do the exact same thing as real switches but VLANS and Etherchannels are supported.

    Hi Rene

    Please help. I have changed the image , idle pc and workingdir and this time around the hypervisor loads to 100 percent but shortly after that it says connection lost. I cant figure out where I am going wrong. Please help. I have tried both the 3725 and 3640 images but it looks like the 3725 is the right image to use according to the "model" field under the router name. Please assist in resolving my issue.

    Renee thanks for this! Great lab.

    I though I’d add few notes though for those who attempt this with real switches.

    I am currently preparing for CCIE so I thought I’d give this a go just to see how rusted I was. I had no major problems doing the lab apart from the following:

    My real switches are 3550s – If you attempt to run HSRPv2, you won’t be able to ping the virtual IP!! I spent 1.5 hours just on that until I gave up and googled the issue only to find this is a bug! Quite annoying as I was timing myself to finish this lab!

    So, please do yourself a favour and run HSRPv1 instead!

    I strongly recommend this lab not for configuration purposes, rather for troubleshooting – specially if you successfuly stop yourself from using versions of “show run”

    Hi Rene,

    I am one of the many who have real equipment but love using GNS3 and your labs.

    1. do you know where I can get or can you provide the switch configs for tshoot lab so I and others can load them into my real switches. Then we can connect them to the GNS3 lab via a cloud.

    2. are you planning to doing trouble shooting labs using GNS3 routers and supping switch configs for people with real switches.

    Keep up the good work and I will be donating again as I love what you are doing.

    I had to add:

    ASW1#vlan database
    ASW1(vlan)#vlan 10
    VLAN 10 added:
    Name: VLAN0010

    etc on appropriate NM16E-SW modules before anything started to happen…which would make sense, sometimes even on a real switch as the startup config isn’t the vlan.dat. No idea how that works in GNS3.

    Glancing over it, it looks like the usual great work Rene delivers, real slick looking diagram. Thanks a lot.

    p.s. on R4 I changed fa1/0 and fa2/0 to Fa0/0 and fa0/1 to reflect the cisco Tshoot topology….(schoonheidsfoutje;).

    Thanks for creating this, but how are you guys pinging from the clients? I just get "Unrecognized host or address, or protocol not running."

    I assume this is because there is no ip routing or IP address assigned to VLAN 1 or similar?

    BTW if anyone has "connection lost to dyamips" errors, double check your console/aux port numbers in the config files and that you have associated external hypervisors configured in GNS3. Also check your working directories and IOS image paths are correct in the config file.

      See my meesage above. I had the same issue. It’s due to the external hypervisors being missing make sure you create the matching localhost ports (both UDP and TCP) under external hypervisors tab in "IOS images and hypervisors" in GNS3

      The console and aux ports in the config file must match those in your external hypervisor settings.

      I actually created 4 hypervisors and changed all the ports in the config file to be more logical.

        Yeah, I had the same problem. My GNS3 install has all defaults set in the preferences section for dynamips ports etc. I have only set the image and project paths etc. To get things working I did the following things:

        setup the 3725 image under “IOS images and Hypervisors” and test it in a blank topology.

        Open topology.net file and edit all instances of the following:

        workingdir = working ( I also created a folder called working in the same location as the topology.net file)

        image = path\\to\\my\\IOS\\images\\c3725-adventerprisek9-mz.124-12.image

        aux = 2501 (go through the entire file and change each instance, incrementing from 2501 upwards. Notice that in the preferences for dynamips, the default starting base aux port is 2501)

        Happy Labbing.
