In his lab videos, he would build a scenario where two paths existed to the same prefix. Then, he would systematically change one attribute (e.g., lowering the MED) and watch the routing table flip, shouting, "See? BGP chose the private jet over the cargo ship!" That visualization sticks.

In the world of internet routing, the Border Gateway Protocol (BGP) is the undisputed king. It is the glue that holds the internet together, governing how data packets travel between autonomous systems (ASes). For network engineers looking to move beyond basic routing protocols like OSPF or EIGRP, mastering BGP is a career-defining skill. In his lab videos, he would build a
On the screen, Jeremy pulled up the network topology. "Look at this. You have a route coming in from AS 100. It’s a fine route. A good route. But then, AS 200 sends you a route. BGP has to pick one. It doesn't use metrics like OSPF, folks. It uses a decision tree. It’s a beauty pageant." : Jeremy Cioara is widely praised for his
