UMGC – Spring 2021 CMIT-455 CCNP ENCOR v8 Chapter #4 Supplement: Multiple Spanning Tree (MST)

In this supplemental video tutorial for Chapter #4 of the ENCORv8 curriculum we take another, deeper dive, look at 802.1s Multiple Spanning Tree (MST). We walk through a brief explanation of its benefits, how it is now included in the IEEE 802.1Q-2005 standard and its advantages over RPVST+ and then walk through all the configuration, validation, and modification steps and we even see what happens when you add an MSTI that is referencing a VLAN that does not exist! 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!
