Introduction

Students receive hands-on development experience with tools and languages relevant to automating the Junos OS platform in a DevOps environment. The course includes an introduction to the Junos XML API, and NETCONF but focuses on using Python, PyEZ, and Ansible to automate Junos. The course introduces students to Junos commit, operation (op), event, and SNMP scripts. JSON, YAML, and Jinja2 are introduced as these languages facilitate Junos automation. The course also introduces the Junos Extension Toolkit and related APIs. Finally, the course discusses the use of JSNAPy and Junos ZTP autoinstallation tools. 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 17.1R1, PyEZ 2.0, Python 2.7, and Ansible 2.3.

Prerequisites & Audience

Students should have intermediate-level networking knowledge and an understanding of the Open Systems Interconnection (OSI) model and the TCP/IP protocol suite. Students should also have familiarity with a programming language such as C, C++, Perl, Python, Ruby, or Java. Students should also attend the Introduction to the Junos Operating System (IJOS) course prior to attending this class. Lastly, a high level understanding of object-oriented programming is a plus, but not a requirement.

Course Benefits

This course benefits individuals responsible for configuring and monitoring devices running the Junos OS.
