This self-paced course provides students with the foundational knowledge to configure, verify, and troubleshoot devices that run Junos OS. Students gain a wide variety of practical experience using the command-line interface (CLI). The course focuses on routers and switches and explains Layer 3 network interface basics, routing tables, static routes, OSPF, Layer 2 switch ports, user accounts, firewall filters, routing policy, and troubleshooting. Particular attention is given to the power of the candidate configuration, rolling back changes, and the power of the Junos OS configuration hierarchy. The course also discusses the key architectural components of the Junos software, the separation of the control plane and the data plane, and the reasons that Junos OS is built for automation. Through demonstrations, students view configuring and monitoring Junos OS and monitoring basic device operations. This course is based on Junos OS Release 22.1R1.10.

Getting Started with Networking (eLearning)

Have you ever wondered how networks work? How two computers communicate? How the Internet works? This course explains these concepts, starting with the basic building blocks of networks, and how Ethernet Local Area Networks (LANs) operate. We discuss IP addressing and subnetting, and how data gets routed from one LAN to another using various Wide Area Networking (WAN) technologies.
