GNS3 ,the most successful network simulation software, announced that they release the new version (GNS3 2.0). Here is the details of the new version :

This is a major milestone for GNS3 – this version brings a new architecture allowing us to add exciting new features and also gives us a solid foundation for more (including Labs).

Major new features of 2.0 include “save as you go” (thanks to the new architecture), smart packet capture, VPCS/clouds/switches templates, a new “cloud node”, a new NAT node and much more. GNS3 now supports a large, and growing list of vendors including Arista vEOS, Cumulus VX, Brocade Virtual ADX, Checkpoint GAiA, A10 vThunder, Alcatel 7750, NetScaler VPX, F5 BIG-IP LTM VE, MikroTik CHR, Juniper vMX and more….

IMPORTANT NOTE to upgrade from 1.5.x and earlier versions of GNS3

Please do not upgrade if you are working on something important like a certification or something else. Understand there is no rollback possible once you open an older project in version 2.0.

 Known bugs and issues

  • A project will be closed if a client closes GNS3 even if two or more clients are connected to that same project.
  • Opening a .gns3 file from Windows explorer will work even when connected to a remote server. This should not be possible and we will add a proper error in a future release.
