In this comprehensive 2-hour tutorial on the Cisco Networking Academy’s CCNP ENCOR v8 Packet Tracer activity 9.2.1 (Multiarea OSPFv2 Configuration) we leave no stone unturned in taking a deep dive look behind the history, challenges and decisions that John T. Moy made to increase the scalability of OSPF during its inception. We examine the OSPF Link State Database (LSDB), we discover and disect the Type 1, 2, 3, 4, and 5 LSAs in detail, explain the reason that each exists, and demystify the reason for each of them. This is all done through the lens of the Cisco Networking Academy’s Packet Tracer 9.2.1 activity. I also provide you with two (2) incredible FREE OSPF resources that any serious network engineer should have in their OSPF toolbox: RFC 2328 (OSPFv2) and the Cisco OSPF Configuration Guide. Enjoy and for those of you celebrating Christmas, I hope you have aa very Merry Christmas and a Happy New Year to all!
***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!
