Inside a Normal area, every type of LSA / Route is allowed. But OSPF also has the ability to designate areas as Stub, or Not-So-Stubby-Areas (NSSA) which allows an OSPF engineer to optimize the types of Routes and LSAs which exist inside an Area. In this video, we explore the five OSPF area types (Stub, Totally Stubby, NSSA, Totally NSSA). We also introduce the concept of a Type 7 LSA, and how they are used within Not So Stubby Areas and translated by ABRs which border an NSSA. This is lesson 14 of the Practical OSPF series. The full series is available here: - Intro - Pre-Requisites: Understanding OSPF LSAs - Topology Introduction & LSA Illustration - Normal Areas - Stub Area (Stubby Area) - Totally Stub Area (Totally Stubby Area) - NSSA - Not So Stubby Area - Type 7 LSA instead of TYpe 5 LSA in NSSA - Type 7 LSAs are translated into Type 5 LSAs - The problem with NSSA Areas - Yes, I just said Not So Stubby Area Areas - Totally NSSA / Totally Not So Stubby Area - 5 OSPF Area Types or 3 - Summary / Outro / Next Lesson === PRE-REQUISITES === LSAs and LSDBs: Designated Routers and Backup Designated Routers (DR / BDR): OSPF Hello Packets: ================ 💬 Join us on Discord: 📜 Studying for the CCNA?
