Introduction to the Junos Operating System (IJOS)
This three-day course teaches students the fundamentals of working with the Junos operating system and configuring Junos devices. The course includes a discussion of the important Junos software architectural elements as well as an overview of Juniper products. User interface choices, with a focus on the command, are important topics.&line interface (CLI), configuration tasks typically associated with device initialization, Basic interface configuration with examples, secondary system configuration, & the fundamentals of operational monitoring and maintenance of Junos devices. Following that, the course delves into fundamental routing knowledge and configuration examples, such as general routing concepts, routing policy, and firewall filters. Students will gain experience configuring and monitoring the Junos OS, as well as monitoring basic device operations, through demonstrations and hands-on labs. This training is based on Junos OS Release 21.1R1.11.
