NETWORK AUTOMATION WITH PYTHON AND ANSIBLE - PYTHON04 Course Outline

(5 Days)

Overview

No two networks are the same! Regardless, your network can be automated with a powerful combination of Python and Ansible across all major (and most minor) network vendors. Lessons and labs focus on using both Python and Ansible to interact with and configure your network devices. At the conclusion of this course you will return to work empowered with skills necessary to automate network management! This class is a combination of live demonstrations and hands-on labs with virtual network devices and endpoints as targets for your configuration.
