CCIE GNS3 Topology
November 3, 2012 76 Comments
This post is dedicated to the best practise for setting up CCIE R&S lab and I want to show you how to set up a practise rack to where you will never ever have to switch a single cable again , no matter what your lab topology looks like , the set up that does it all !
The only difference between this one and the previous topology is that I have changed the symbols so it’s easier to differentiate devices on screen but except for that it is all the same and no other changes have been made. Further down I have added initial configs files for CBT Nuggets CCIE series, INE , IP Expert and Narbik (Super Lab)
CCIE R&S topology I have built and been using on GNS3 for the CCIE journey.
So far I have seen and used topologies with a GNS3 built in Frame Relay switch plus 6 routers (INE spec) so I’ve decided to create one with CLI configurable Frame Switch and connect all devices in a way so that you are able to create any topology without the need of changing the cabling etc … The reason for 17 devices being used is because some of the CCIE preparation series like IP Expert, CCIE Service Provider see image have topologies with more than 6 routers which is expectable from Cisco in the current v4 Lab exam but the idea is so we can practise not only INE lab scenarios with 6 routers but also IP Expert lab scenarios where Quadruple CCIE Scott Morris uses topology with 9 routers instead and of course for us to become more familiar with the actual frame relay switch configuration.
In case you having some issues with connectivity or the gns3 is crashing just after you start the topology, change the (127.0.0.1 with localhost) or vice versa in the .net file.
Please remember, that you can’t run most of layer 2 technologies command, since GNS3 (and all emulators) just do the software, where switches are mostly ASIC programmed to run the features.
This topology is customizable which means that with a little tweaking (vlans, ip addreses, frame switch config etc…) you will be able to practise any R&S scenario you can possibly find out there.
Firstly power up the 4 switches and copy and paste ccie_all_vlans . It will set you up for each of the below lab.
See intial configs below – INE lab specification VOL1
See intial configs below – IP Expert lab specification VOL1
See intial configs below – CBT Nuggets lab specification (CCIE R&S LAB SERIES)
See intial configs below – Narbik Super Lab specification (CCIE R&S LAB SERIES)
SW1 – SW2 – SW3 – SW4
See below GNS3 net file. Simply go to previously specified by you GNS projects folder on your hard drive , right click on a net.file , edit network file , copy/paste the output from the one provided below ,change the image path to the path directory where you store your IOS images and change the workingdir path pointing to wherever you have saved provided above configs , save it the net.file under another name to avoid removing some of your own by mistake and there you have your CCIE topology. Launch GNS3 , literally copy and paste one of the provided above configs depending of course on what series you are watching at the time and start labbing !
I have not been able to upload actual GNS3 file however I personally always take above approach or literally build a topology from scratch cause then you know what exact settings you need to set on your machine , idle pc etc … and most importantly your mind visually memorizes connectivity between devices. Simply try an approach as if you were sitting at the CCIE lab exam, read the net.file and subconsciously make a mental picture of the topology.
If you’re already in possession of the INE , IP Expert Workbooks , CBT Nuggets CCIE or Narbik video series then these initial config files will save you at least 1.5hrs of labbing if not more!
