BGP has a unique danger: If you misconfigure OSPF, you break your office. If you misconfigure BGP, you break the internet (or at least your upstream connectivity). Jeremy’s training focuses on the "safety rails"—the concept of neighbor shutdown and soft reconfiguration—while removing the fear factor through confidence-building labs.
While exam codes change, the underlying mechanics of how autonomous systems exchange routing data across the globe have remained remarkably stable. Jeremy Cioara’s CBT Nuggets CCIP BGP (642-661) training acts as a masterclass in fundamental networking concepts. By combining his engaging conceptual breakdowns with modern hands-on lab practice, you can build a rock-solid understanding of BGP that will serve your networking career for decades to come.
Used to tell your AS how to exit the network.
While the exam code is legacy, the core concepts of BGP taught by Jeremy Cioara remain highly relevant. BGP is a stable protocol; the fundamentals covered—such as path selection, attributes, and neighbor relationship management—are fundamentally the same in modern Cisco IOS XE, XR, and NX-OS. This training is an excellent choice for:
Tagging routes with administrative labels to apply policies globally across the network fabric. How to Modernize the 642-661 Knowledge
Complex path selections are broken down via real-time whiteboard drawings, helping students visualize packet flows across autonomous systems. Core Technical Domains Covered in the 642-661 Course
Jeremy Cioara takes learners through a logical progression of BGP topics, from basic setup to advanced policy control.
This is where shines. As one of CBT Nuggets' most beloved trainers, Cioara brings an unparalleled level of energy, passion, and real-world context to the whiteboard. 1. High-Energy, Conversational Delivery
While Cisco eventually retired the CCIP acronym to evolve its curriculum into the CCNP Service Provider track, the foundational physics of BGP did not change. The internet still runs on the exact same BGP attributes, state machines, and path selection criteria taught in the 642-661 syllabus. Consequently, this training remains deeply relevant for anyone preparing for modern CCNP Enterprise, CCNP Service Provider, or even CCIE lab exams.

Anyone can memorize a Cisco IOS command, but Cioara focuses on the underlying design principles. He teaches why an ISP would choose one path over another, why certain attributes take precedence, and how a single misconfiguration can inadvertently take down a client's internet connectivity.
