This lab is a proof of concept in using Cisco networking equipment and the OSPF (Open Shortest Path First) routing protocol to perform inter-VLAN routing. This is achieved using trunk ports and router sub interfaces. It is a great way to show efficiency in subnetting and enterprise networking. I do have other labs and demonstrations of other routing protocols such as BGP, EIGRP, and more. For demonstration purposes, I revised the lab to be displayed for educational purposes.
