What made this CBT Nuggets series iconic was the practical, lab-driven approach. Instead of reading dry slides, Cioara builds topologies from scratch using Cisco IOS commands. Establishing a Basic eBGP Neighbor
Because iBGP requires a full mesh topology by default (due to the iBGP split-horizon rule), scaling it inside a large network is highly problematic. The series tackled the two primary solutions required for the exam and real-world ISP work: cbt nuggets cisco ccip bgp 642661 by jeremy cioara work
This article explores the structure of that classic course, why Jeremy Cioara's methodology became legendary, and how the core concepts taught in the 642-661 curriculum still apply to modern enterprise and service provider networks today. The Legacy of Cisco CCIP and the 642-661 Exam What made this CBT Nuggets series iconic was
Jeremy often described himself as a "friend to giant tomatoes, including ones named Bob," a quirky personal touch that made him feel less like a distant expert and more like a mentor. He openly shared his passion for IT by comparing building a network to playing a city-building simulation game. In this analogy, he doesn't just admire his perfect cities; he enjoys it when a "natural disaster" button is clicked, sending a "tornado" through his network. This, he argues, is where the real learning happens—seeing how the ecosystem survives and fixing what breaks. This passion, humor, and infectious love for the subject matter are what transformed his CCIP BGP series from just another training course into a legendary learning resource. He didn't just teach BGP; he made you fall in love with it. The series tackled the two primary solutions required
Unlike internal protocols that rely purely on basic metrics like bandwidth or delay, BGP uses a strict list of architectural attributes to choose the best route. Cioara's course meticulously visualizes how a router evaluates these variables: (Cisco proprietary, local to the router)
While Cisco retired the specific 642-661 exam in July 2012, replacing the CCIP track with the certification, the foundational knowledge in Jeremy’s course remains a cornerstone for network engineers today. Why This Specific Series Still Matters
