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

The course provides a brief overview of the Juniper products and discusses the key architectural components of the Junos software.

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

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

Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos OS and monitoring basic device operations.

This course is based on Junos OS Release 21.1R1.11.

The Introduction to the Junos Operating System (IJOS) is an introductory level course.
