Welcome to the Juniper Networks Introduction Series! If you’re like me, you’ve been networking for a while. Sooner or later, you will come across Juniper devices, and may find them to be quite different to what you’re used to. This series will build on the skill that you already have, to get you Juniper ready. It will also prepare you for the JNCIA-Junos exam, if that’s something that interests you. Each video is designed to be as short and to the point as possible. They are arranged into five categories; The Basics, Device Configuration, Architecture, Routing, and Monitoring/Troubleshooting. Each video comes with additional resources, including study notes, links for additional reading, labs, quizzes, and flashcards. #junipernetworks #networkdirection #networking #informationtechnology #junipernetworksintroduction

Junos and IOS take very different approaches to operating system design. The two main approaches are monolithic and modular. Monolithic is a simple but old design strategy. Basically, everything is handled in the kernel. This comes with downsides. For example, a fault in one component can take down an entire system. A modular operating system separates parts, meaning that different components, including drivers, are independant. The chassisd process brings line cards and other components online. Dcd controls devices and interfaces. Mgd is used for handling incoming management traffic Rpd manages all routing protocols Snmpd manages SNMP requests, responses, and traps.
