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

Firewall filters are like ACLs. This can be to permit/deny traffic, or as a component in some policy (such as Class of Service, or a routing policy). The main component of a filter is a ‘term’. These are the rules. They match conditions, and apply an action. Use the ‘from’ statement to match traffic. Use the ‘then’ statement to apply an action. Terms are applied in the order they are listed in the filter. There is an implicit deny term at the end of the list. Sample actions include accept, reject, discard, syslog, sample, and next-term. Some actions are terminating (no further action is taken), and others are non-terminating (more actions will take place). Multiple filters can be applied to a single interface. This can be done by nesting them, or by creating a list of filters.
