Introduction To Junos Platform Automation And DevOps.

GK# 100558

Course Overview

TOP

This three-day course provides students with introductory knowledge of how to automate Junos using DevOps automation tools, protocols, and technologies. Students receive hands-on experience with tools and languages relevant to automating the Junos OS platform in a DevOps environment.

The course includes an introduction to the basic DevOps practices, Junos APIs, and NETCONF. It then focuses on using Python, PyEZ, Ansible, and REST API to automate Junos. XML, JSON, and YAML are introduced as these languages facilitate Junos automation.

Through demonstrations and hands-on labs, students will gain experience in automating the Junos operating system and device operations. This course uses Junos OS Release 18.1R1, Junos PyEZ 2.1, and Ansible 2.5.
