I’ve run across him through the years, but never really checked him out. His free CCNA YouTube course is cool for two reasons…so far.
- This Cisco Packet Tracer that he introduced me to is awesome. Because it takes the OSI layers which to me has been abstract, and makes it clear as you can watch the packets or frames travel to a destination and you can see the layers at the next stop.
- His seemingly genuine excitement in explaining things.
I took a Cisco router configuration class probably 25 years ago. But I didn’t understand things the way I should. Because it was abstract to me. I wasn’t the network guy but I was helping out the network guy. Probably because they could see I had an enthusiasm for almost anything related to a computer. They sent me to Cisco school and I understood it good enough to configure, and assign IP address to the routers for 50 branch routers. But I didn’t understand it like I wanted to. And just when I though I was understanding things better a Cisco engineer would come in and start talking about things that made me feel like a network amateur. So all this Wireshark, GNS3 and Cisco Packet Tracer stuff is pretty cool.
