By now you will have noticed that when you open a GNS3 project, you have to select a file with a .net
extension, usually topology.net
.
Firstly, understand that the topology file does not have to be called topology.net
. But as GNS3 evolved, it became more practical to simply call the file topology.net
, and since GNS3 v0.8.3 has only ever saved a new topology file as toplogy.net
. You may find older topologies or even manually handcrafted files, usually with a .net
extension that will open happily in GNS3.
In fact, the .net
file format actually belongs to Dynagen, and you can take any .net
file produced by GNS3 and use it directly with Dynagen independently of GNS3. To get a full understanding of the sections of the file that both GNS3 and Dynagen use and interpret, see Greg Anuzelli's tutorial available at: http://dynagen.org/tutorial.htm, but here is a brief overview.
The topology.net
file created by GNS3 has two parts. Here is a sample:
