CCNP TSHOOT GNS3 Topology

Written by Rene Molenaar on . Posted in FAQ

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 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 3640 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.
  • 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. I left it this way but keep it in mind.

IOS:

c3640-jk9s-mz.124-16.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

    Good luck on your next track! (CCIP maybe? :P)

    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

    Hi Rene

    Thank you so much for the lab, and thank you Jeff for you help finding the problem , after set up the configuration under ospf 1 router 3 area 34 nssa no-summary
    I can ping from both client 1 and client 2 to the server.

    Best Regards

    Hi Chris,

    If you open up a new forum topic I can help you with this, i'll need two things:

    - topology.net file of a lab you created yourself.
    - my topology.net file that you edited.

    Rene, the same IOS as you have listed.

    All your other labs open just fine. Just the TSHOOT.
    I have 16gb of RAM and a quad core proc. Should open just fine.

    hi Rene,

    From your config on DSW1, how come you have Po2? Thought it should only have Po1-3-5? Thanks.

  • avatar
    ReneMolenaar
    2012-04-23 12:37:14

    Hmm let me check, DSW1 only should have PO13,PO14 and PO12 according to the Cisco topology.

    Hi Rene, sorry for asking too many questions. Is it possible to configure portchannel between DSW1 and DSW2 with ipv6? Because based from TSHOOT topology it does have portchannel on it. I have tried but it seems im getting L2 error. Not sure if you can make it work..... Thanks!

    2012-04-24 10:33:26

    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.

    Hi Rene, you are right. Im having problem with L3 etherchannel. Im not able to enter this command....

    !
    interface Port-channel3
    description DS1 to DS2
    no switchport
    ip address 10.2.4.13 255.255.255.252
    ipv6 address 2026::3:1/122
    ipv6 rip TSHOOT enable
    !
    !
    interface FastEthernet1/13
    no switchport
    no ip address
    channel-group 3 mode on
    !
    interface FastEthernet1/14
    no switchport
    no ip address
    channel-group 3 mode on
    !

    Not sure if my config is correct :)

    Hi
    I downloaded GNS Layer 3 Tapology for Tshoot exam and also downloaded image "c3640-jk9s-mz.124-16.image".
    When I run tapology I recieve the following error.
    Local IOS image /DATA/GNS3/IOS/C3640-JK.BIN cannot be found for hypervisor 127.0.0.1:7200.Can anyone advice how to rectify this problem.

    Hi Mahmood,

    Take a look at this link:

    It fixes most of the issues.

    Weird question to ask. Do this topology file work on the newest verision of GNS3. Since I uninstalled and installed the newest verision the .net file opens GNS3 but then closes.

    Next I open gns3
    Open>topolgy.net file
    but message displays Open permission denied.

    Hi Angpipp01,

    May I ask what did you change in the topology file? I'm also experiencing the same problem as what you have experience before. I also tried to edit based on what you said. I change the path for the config but I'm not sure if that was what you have change. hope you can help. thanks!
