Course Description

Learn Network Programmability and Network Automation using GNS3 and Python.

Want to program networks using Python, but not sure where to start? Well, this course will show you how you can start programming Cisco networks within 20 minutes.

This course was created for network engineers. There are too many other Python courses out there that try to make network engineers software developers. Instead of teaching network automation, they teach you Python theory. This course is different. 

This course is practical. I won't talk about programming in abstract terms and make you wait before you can start automating networks. I will show you how you can quickly and easily start network programming by using GNS3, Cisco IOS and Python.

You will see demonstrations of the configuration of both Cisco routers and switches in GNS3. For example, how to configure multiple VLANs on a multiple switches, or how to configure OSPF on a router and more.

This course shows you practical examples of using Python to programmatically configure Cisco network devices rather then just talking about it.

The days of configuring Cisco networks only with the command line interface (CLI) are drawing to a close. You need to add network programmability using Python and APIs to your skill set.

Learn how to automate networks using:

- Telnet

- SSH

- Paramiko

Netmiko

NAPALM

pyntc

Tools such as NAPALM and pyntc make it easy to configure and interact with network devices using an API such as NETCONF or using SSH. Don't reinvent the wheel. Use the tools available to you to quickly and easily automate your networks.

Some comments about the course:

"Knowing the material from just the first video would have saved me hours of work and rework in the past." 

"It's the easiest, most fun, and most valuable course I've completed yet on Python Programming for Networking. Love it! Thanks again David!!!" 

"Excellent course on Network Programming using Python with lot's of practical network configuration examples."

"Great way of explanation.Nice video and inspiring words! Thank you so much David. You are genius."

"I've been doing network automation for a while, even so, I've learned new things through this course. The instructor start from a basic example, adding improvements in each step. It's a skill that's worth it."

"A must for all network engineers who want to learn python!!! I had very "very" basic programming skills, and couldn't just get the bridge between network and programming (mainly Python - since that's where the hype is now), this course was amazing, I have never been glued to a training course since I can remember. The couple of things I loved the most about this course: 1- David's clear voice. 2- Real world application, not only will David interduce different real-world practical modules that you can import and use, but he shows you how to apply them on ios devices."

"Excellent course on Network Programming using Python with lot's of practical network configuration examples. High quality content."

the content is great. I would add one more star to make it interactive with assesments and exercises. I would add another star for organizing the content according to relevance in 2026; content can be simply move to a grandfather category/lab/chapter. Thank you for all the work.

By Daniela Rivera on 6/25/2024

The course is really nice, however I see no point whatsoever in taking it. I feel I wasted money actually. All the contents can be found in the instructor's youtube channel, or at least the majority. Also in the videos he refers often to the "resources linked in the description", which are absent in this udemy course. Many of the links to files with configs have been deleted and the content of the course itself needs to be updated to the newest versions of python and libraries being used.

By Tayo Adelabu on 5/13/2020

If you have very basic python knowledge, this is enough to understand the initial python exercises. The python theory in the later part of the course is very good as it bridges the python knowledge gap used in the exercises.. Excellent instructor - clear and at the right pace! Issues with python 3 e.g. Netmiko no longer seem to work on Python 3.

By Eric Crosby on 12/22/2019

This is a very good course. The information is practical and well presented. I found some of the Ubuntu configuration did not work well exactly as proscribed in the GNS3 documentation but think that was due changes in the Ubuntu. I am enjoying this course and learning useful information.

By Dennis J McKay on 8/27/2019

Of all of the training I have found for Python in regards to network engineering this is hands down the best. None other even compare. I love his training technique of getting you out there riding a bike and falling off. It is the best way to learn. I am recommending it to all of my colleagues and friends.

By Bruno Rodrigues de Lima on 7/31/2019

Amazing content and easily explained. Congratulations to David Bombal. The only negative point is the pictures shown while he is commenting something, in my personal point of view, they are unnecessary but it doesn't affect anything at all about the course content and quality. Congrats.

By Johan Smit on 5/21/2019

Dit is echt top! Precies wat ik zocht, praktisch en informatief. De commando's worden soms wel erg snel uitgevoerd, waardoor je er makkelijk één over het hoofd ziet als je direct mee wilt doen met een labje. Commandos zijn wel bijgevoegd als bijlage, dus dat is echt handig. Fijn ook dat niet alles meteen in 1x van je wordt verwacht en dat je ook aangeeft dat je erin moet groeien, maar soms wordt dat wel iets teveel herhaalt waardoor je veel naar hetzelfde zit te kijken.

Hi Initially after buying the course, i thought of applying for refund. But trust me guys, complete the course from first video till end. This course is worth for the amount you pay. Course is really helpful. I created 4 scripts after learning this course. Thanks a lot David Bombal. Planning to learn SDN in future.

By Ryan Gorden on 7/19/2018

I would recommend David python course to anyone. After going through this course I was able to apply these concepts at work and be way more efficient. I have also wrote programs for friends to handle network task based off what I have learned in this course. This course has very going.

By Patrick OConnor on 3/8/2018

This was my first course concerning Python. I have been a network engineer for the last 10 years. This instructor presented python and what it could do for me in a great fashion. Instead of explaining what python is and how it works. He shows what it can do and it makes sense! This kept me engaged and when all the networking example were finished. He goes on to explain the fundamentals of Python. At this point i was ready to learn those fundamentals and learn what else I could do with this newly found knowledge. Great Instructor!!
