If you need a point of contact for all things networking, then look no further than Ivan Pepelnjak. Ivan is the webinar author at ipSpace.net where he is working on making networking an approachable subject for everyone. From teaching to writing books, Ivan has been at it for a long and storied career, and as a de facto go-to for networking knowledge, you can’t beat him. In this Summer Replay of Screaming in the Cloud, Ivan and Corey discuss Ivan’s status as a CCIE Emeritus and the old days of Cisco. Ivan also levels his network engineering expertise and helps Corey answer some questions about BGP and its implementation. Ivan aptly narrows it down into “layers” that he kindly runs us through. So tune in for a Dante-esque descent into BGP, DNS and Facebook, seeing out the graybeards of tech, and more!
