In this comprehensive supplemental tutorial to the Cisco Networking Academy's CCNP ENCOR v8 Packet Tracer activity 8.2.1 (Configuring Single Area OSPFv2) we will once again go into great detail on the configuration basics of the Open Shortest Path First (OSPF) dynamic routing protocol. We cover Router ID semantics, passive interface configuration considerations, the Designated Router (DR) and Backup Designated Router (BDR) semantics, the Link State Database (LSDB), RFC 2328, John T. Moy's 'Anatomy of a Routing Protocol' book, and much, much, more. Enjoy!

***This video is an in-depth tutorial and is far more than simply an answer key to the aforementioned Packet Tracer activity. This tutorial is being made to assist my UMGC CMIT-455 learners in their journey through the ENCOR v8 material so, if you are just looking for a shortcut or easy answers for the activity, this is not the video you should watch. However, if you are looking to gain a deeper understanding on inter-VLAN routing configuration and designs, my hope is that this will increase your comprehension and help you to become a better and more effective network engineer. Enjoy!

*This techtorial/Packet Tracer activity is all done running Cisco Modeling Labs (CML) v2.1.1-b19, some physical routers in my Evil Command Center Lab and/or Packet Tracer version 7.3.1.0362 (for the Mac) which was just recently released! The MINIMUM version you can use for any of the new CCNAv8 curriculum activities is Packet Tracer v7.3.0! Be sure to leave your feedback and questions below and I hope I have earned the privilege of your time!
