TL;DR BGP wins in modern networks because it scales policy, not topology. Use communities to encode intent once and enforce it at the right boundaries; use iBGP with route reflection to distribute reachability cleanly; and reserve local-pref as your go-to knob for deterministic traffic engineering. For overlapping IPs (hello, mergers), communities plus a staged renumber/NATContinue reading “What is BGP?”

Bridging the Divide Between Developers and Network Engineers
In a recent episode of The Art of Network Engineering podcast, hosts Andy Lapteff and Jeff Clark welcomed Erika Dietrick—known online as “Erika the Dev”—to tackle a long-standing cultural and technical divide in IT: the disconnect between network engineers and software developers. Erika, a former Developer Advocate at Cisco with roots in both software developmentContinue reading “Bridging the Divide Between Developers and Network Engineers”
Fork Yeah! Git in Network Engineering
Git has revolutionized software development over the past two decades, but many network engineers still view it as a tool exclusively for developers. This mindset creates an artificial barrier between networking professionals and powerful tools that could dramatically improve their workflows and productivity. As we explored in our recent episode of The Art of NetworkContinue reading “Fork Yeah! Git in Network Engineering”
The Resistance to Network Automation: Understanding the Psychological and Practical Barriers
Network automation has long been heralded as the game-changer that would revolutionize networking. It promises easier management, fewer errors, and more time for strategic, high-value work. Yet, despite these clear advantages, adoption rates remain surprisingly low, with estimates hovering around just 20-30%. Why is this shift, which seems so inevitable, still met with such resistance?Continue reading “The Resistance to Network Automation: Understanding the Psychological and Practical Barriers”
Ethernet vs. InfiniBand: The Battle for AI Networking Supremacy
As artificial intelligence (AI) advances at a frantic pace, so do the demands placed on network infrastructure. The age-old debate between Ethernet and InfiniBand is taking center stage once again, particularly as AI workloads push the boundaries of performance, scalability, and efficiency. In our latest podcast episode, industry experts dive into this very topic, exploringContinue reading “Ethernet vs. InfiniBand: The Battle for AI Networking Supremacy”
CCNA Series – Automation and Programmability
In this article, we are going to discuss several parts of Section 6 – Automation and Programmability of Cisco CCNA Syllabus. Programmability and Automation are two huge and very hot topics in the world of Networking. Having Programmability and Automation skills is practically a requirement – so many organizations are adopting it. This article hopesContinue reading “CCNA Series – Automation and Programmability”
