GNS3 V1.5.2 与IOU L2 L3的集成

After some years, it’s time again to preparefor my next CCNP re-certification. I was pleasantly surprised that running full-featured Cisco L2 p_w_picpaths is now made entirely possible with the new “IOS on Unix (IOU)” function on GNS3. I documented my new setup here according to the GNS3 v1.5.2 running on a Windows x64 host.You’ll need to get hold ofthe following filesbeforehand:Cisco IOU L2 and L3 p_w_picpaths (byGoogling)Cisco IOU license fileiourc(see thisforum discussion)Once you have obtained the above files, you can now proceed withthe following steps:Download and install the all-in-one GNS binaries fromgns3.comDownload the GNS3 VMOVF p_w_picpathas well. Ensure that the version of both GNS server and the OVF p_w_picpath must match i.e. 1.5.2 in this case.Download and install either VMWare Workstation Player or Oracle VirtualBox in your host.Import the GNS3 VM OVF into either virtualization software and start running it. Ensure that at least one network interface is of NAT type (enabled by default)Note down the IP address stated on the screen on the GNS3 VM.Start GNS3 and go toEdit | PreferencesEdit the path tovmrunfor VMWare or the path toVBoxManagefor VirtualBox.Go toServer | Remote Servers.

For example:gns3@gns3-vm~#sudo hostnamectl set-hostname gns3-iouvmgns3@gns3-vm~#bash
