In this series of videos I will show you how you can quickly and easily program Cisco networks using Python. ================================ Script on GitHub: ================================ https://github.com/davidbombal/pythonvideos/commit/003a9a6fe8f7de5543a902c8eb88a4f78a81f143 Transcription: This is one of the multiple videos teaching you network programmability using Python and GNS3. In the previous video I showed you how to use Netmiko to configure a single IOSv switch in GNS3. Now we'll extend to the topology and configure three switches. So I've got three switches booted and configured for SSH in GNS3 and I can now configure them through Netmiko. Netmiko makes it easy. This is the configuration for switch 1 here's the configuration for switch 2 Here's the configuration for switch 3. If I have additional switches I would simply configure those additional switches in the Python script and now what I can do is create a variable that contains IOS v layer 2 switch 1 switch 2 and switch 3 and then I can run a loop. So I can say four devices in all devices, in other words these three switches we're going to connect to those devices and then I'm going to run a sub loop where I create 20 VLANs on each of those switches. So it's quite a simple script which I'll now copy. Here's my Ubuntu host I've got a script called a Netmiko1. So let's create another one called Netmiko 2 and I'll paste that script in. The script is once again available on github and I've referenced it below this video. So there's the script. Now before I run the script I'll reduce the number of VLANs to 5 so that you don't have to watch me wait for the VLANs to run. So now python netmiko2 before I run the script, let's have a
