Junos OS Evolved for Cloud Networking (JECN)

 

Résumé du cours

This three-day course is designed to provide students with the knowledge required to work with the Junos OS Evolved. The Junos OS has evolved since its creation to leverage advanced operating system and platform technologies. As it has evolved, key fundamental concepts have changed, and continue to change, in how the operating system functions and is used by administrators. This course explains the key changes to the operating system, and how the configuration and administrative tasks performed on Junos Evolved differ from Junos OS configuration and administrative tasks. This course includes a particular focus on expanded support for third-party applications on the Junos platform, including Docker container support, and introduces students to new troubleshooting commands and tools available in Junos Evolved. Through demonstrations, students will gain experience with updated operating system features. This course is based on Junos OS Evolved release 21.2R1.
