I thought I’d share the GNS3 files that I used to study for my CCNA. This isn’t based off of any lab that I know of, I just made them up. I created a blank Frame Relay network and a blank router network and practiced configuring them for Frame Relay hub and spoke, NAT, DHCP server, RIPv2, single area OSPF, EIGRP, and security.
GNS3 Frame Relay Network
What You Get
These are blank files in that they are connected, have host names, IP addresses and the DLCIs are configured in the Frame Relay network. They’re basically ready to configure for the items listed above. All passwords are cisco. The drawings have the IP and DLCI information on them.
You can download the zipped file here (7 MB). You can unzip them and copy them to your working file such as /Applications/Dynagen/tmp/ or wherever you put your working files. I used 3640 routers, but you can open the config files and modify them for whichever router you use.
You should be able to save the files, start GNS3, and then start the devices and be on your way. For Mac users, here is a link to setup your default terminal to open new tabs for each device.
Strategy
I did it this way to save time setting up practice networks. I used these blanks to get started, and then I’d configure NAT and EIGRP or maybe just NAT and a DHCP server. These were small, quick setups so I wouldn’t save my work after I made changes. If I were to do this for CCNP or CCIE practice, I’d save a blank file like this and save the work using a new file name. Just my thoughts. Let us know if you have a way that works better for you.
Disclaimers
I don’t think it matters, but these were created on a Mac.
I’m just throwing these out there for your use if you want them, and use them at your own risk. I am not including the Cisco IOS, or any warranties of any kind. I am happy to answer any questions you might have on a best effort basis.
