Introduction to the Junos Operating System (IJOS)

Introduction to the Junos Operating System (IJOS)

Course overview

This three-day course provides participants with the basic knowledge required to work with the Junos operating system and to configure Junos devices.

The course provides a brief overview of Juno’s device families and covers the key architectural components of the software.

Key topics include user interface options with a heavy emphasis on the command-line interface (CLI), configuration tasks typically associated with initial setup of devices, the basics of interface configuration with configuration examples, secondary system configuration, and the basics of operational monitoring and maintenance of Junos devices.

The course then delves into basic routing knowledge and configuration examples including general routing concepts, routing policy, and firewall filters.

Through demonstrations and hands-on labs, participants gain experience in configuring and monitoring the Junos OS as well as overseeing basic device operations.

Introduction to the Junos Operating System (IJOS) is an introductory course and is based on Junos OS Release 15.1X49.
