In this comprehensive and exhaustive techtorial on Packet Tracer activity 2.4.11 (Modify Single-Area OSPFv2) we take a deep dive into the the new Cisco Networking Academy CCNAv7 Enterprise Networking, Security, and Automation (ENSA) course curriculum! In this techtorial you will learn how to manipulate OSPF timer values like the HELLO and DEAD intervals, you will learn the semantics behind which values need to match in order for an OSPF adjacency to be established and to be maintained, we will take a deep dive into Layer 3 traffic engineering with OSPF and discuss the reasons why manipulating the bandwidth setting is not always the correct way to approach this task, and we discuss how to validate and verify your work. This techtorial/Packet Tracer activity is all done running Packet Tracer version 7.3.0 which was just released this week and is the MINIMUM version you can use for any of the new CCNAv7 curriculum activities! Be sure to leave your feedback and questions below and I hope I have earned the privilege of your time! Enjoy!
