The Art of Network EngineeringAuthor: Andy and Friends
The Art of Network Engineering blends technical insight with real-world stories from engineers, innovators, and IT pros. From data centers on cruise ships to rockets in space, we explore the people, tools, and trends shaping the future of networking, while keeping it authentic, practical, and human.We tell the human stories behind network engineering so every engineer feels seen, supported, and inspired to grow in a rapidly changing industry.For more information, check out https://linktr.ee/artofneteng Language: en Genres: Business, Careers, Technology Contact email: Get it Feed URL: Get it iTunes ID: Get it |

What is IS-IS?
Wednesday, 17 December, 2025
Send us a textMost network engineers know BGP, OSPF, and maybe EIGRP, but far fewer have hands-on experience with ISIS. In this episode of The Art of Network Engineering, Andy Lapteff sits down with Russ White and Mike Bushong for a deep, opinionated, and refreshingly honest discussion about routing protocol design in modern data centers.We explore why BGP has become the default hammer for every networking nail, what we lose when we blend underlay and overlay into a single protocol, and why some of the largest networks in the world still rely on IS-IS for simplicity, scale, and resilience.This isn’t a “which protocol is best” argument, it’s a design conversation. One about failure domains, operational reality, education gaps, and why many engineers never learn the protocols that quietly power hyperscale networks.In this episode:Why BGP is policy-rich but intentionally slowThe architectural value of separating underlay and overlayHow ISIS works and why it’s simpler than you thinkTLVs, scalability, and protocol evolutionWhy familiarity often beats good design (for better or worse)Where RIFT fits and where it doesn’tThe cost of losing deep protocol knowledge as engineers retireIf you’ve ever wondered why networks are designed the way they are, or if you’ve felt uneasy about “just using BGP everywhere,” this conversation is for you.Subscribe for more conversations where technology meets the human side of IT.This episode has been sponsored by Meter.
