Jeremy Cioara is arguably the most charismatic instructor in Cisco history. His teaching style is the primary reason to watch this series, even today.
If you have ever watched a CBT Nuggets video, you know Jeremy Cioara immediately. He brings an unmatched energy to technical training. Unlike monotone instructors who read slides, Jeremy uses whiteboards, real equipment, and a storytelling approach.
What makes Jeremy’s teaching unique:
In the Cisco CCIP BGP 642-661 series, Jeremy is at his peak. He breaks down the BGP decision process—often a nightmare for students—into a simple, logical flowchart that stays with you long after the video ends.
The 642-661 curriculum focuses specifically on BGP configuration and troubleshooting on Cisco routers. The course typically covers the following core domains:
1. BGP Fundamentals & Theory Cioara begins by demystifying the concept of Autonomous Systems (AS) and the differences between Interior Gateway Protocols (IGPs like OSPF/EIGRP) and Exterior Gateway Protocols (EGPs). He explains the BGP path selection process—a notoriously difficult concept for students—in a way that is intuitive and logical.
2. Basic BGP Configuration Viewers follow along as Cioara sets up a lab environment. He covers:
3. Advanced BGP Attributes The meat of the course lies in the manipulation of BGP attributes. Cioara dives deep into:
4. Route Filtering and Manipulation A critical skill for any service provider engineer, the course covers how to control routing updates using:
5. BGP Scalability (Route Reflectors and Confederations) To address the "full-mesh" IBGP scalability problem, the course explains and demonstrates how to configure Route Reflectors and Confederations, which are essential for larger enterprise and ISP environments.
6. Multihoming Cioara covers the practical scenarios where an enterprise connects to two different ISPs. He discusses default routing versus full internet routing tables and the policy decisions required to ensure redundancy without creating routing loops.
If you want, I can produce a condensed study checklist, lab topology with step-by-step configs, or a set of practice questions based on the course—tell me which one.

Clear Visuals: Cioara uses hand-drawn diagrams that help visualize complex path selection and neighborship processes. What to Watch Out For
Depth vs. Detail: While excellent for concepts, some reviewers find that CBT Nuggets courses can lack the minute technical details required for passing modern, high-level exams like the CCNP or CCIE without additional reading.
Legacy Context: Because the CCIP track was being redesigned at the time of release, this series deliberately focuses on BGP knowledge rather than specific certification requirements.
Supplementary Needs: It is highly recommended to pair these videos with labbing—such as GNS3—and an authoritative text like Jeff Doyle's TCP/IP Illustrated to master the protocol fully. Recommendation
This course is a must-watch for anyone new to BGP who finds traditional technical training too dry. It provides the "big picture" needed to then dive into deeper technical documentation.

The Cisco CCIP BGP 642-661 exam may be retired in the eyes of Cisco’s official certification roadmap, but the knowledge contained within Jeremy Cioara’s CBT Nuggets course remains the "Gold Standard" for anyone wanting to truly understand the backbone of the internet. Jeremy Cioara is arguably the most charismatic instructor
Whether you are a network engineer brushing up on service provider technologies or a student of the CCIE, this specific training series is legendary for its ability to turn one of networking's most intimidating protocols into something digestible and even fun. Why This Specific Series Matters
Border Gateway Protocol (BGP) is fundamentally different from IGP protocols like OSPF or EIGRP. It doesn’t just find the "fastest" path; it finds the path that aligns with business policies.
Jeremy Cioara is famous for his high-energy, whiteboard-heavy teaching style. In the CBT Nuggets BGP 642-661 series, he moves beyond simple command syntax. He explains the why behind BGP—why we use autonomous systems, how the internet stays stable, and how path attributes manipulate the flow of global traffic. Key Topics Covered in the Training
The course is structured to take you from a "BGP Novice" to a "Policy Architect." Here are the core pillars Jeremy covers:
BGP Fundamentals & Peering: Understanding the difference between Internal BGP (iBGP) and External BGP (eBGP), and the strict rules governing how they form neighbor relationships.
The BGP Table & Route Selection: This is the "meat" of the course. Jeremy breaks down the complex 13-step BGP best-path selection process (Weight, Local Preference, AS-Path, MED, etc.) using real-world analogies.
Policy Control with Route Maps: You learn how to use prefix lists and route maps to filter updates and influence how traffic enters and leaves your network.
Scalability (Reflectors & Confederations): In large networks, the full-mesh iBGP requirement becomes impossible to manage. This series explains how to scale using Route Reflectors and Confederations.
Connecting to the Internet: Real-world scenarios involving single-homed, dual-homed, and multi-homed connections to ISPs. The "Jeremy Cioara" Factor
What makes this CBT Nuggets series stand out from a dry technical manual is Jeremy's enthusiasm. BGP can be a "dry" subject involving thousands of lines of configuration. Jeremy uses his signature "doodles" and real-world stories from his time in the field to show you what happens when a BGP configuration goes wrong—and how to fix it. Is It Still Relevant?
While the 642-661 exam number has been replaced by newer CCNP Enterprise (ENARSI) and Service Provider (SPRI) exams, BGP itself hasn't changed. The core mechanics of the protocol—attributes, finite state machine, and path selection—are exactly the same today as they were when this course was filmed.
If you are looking for a foundational deep dive that makes the concepts "stick," this legacy CBT Nuggets series is still one of the best resources available. Final Thoughts
The CBT Nuggets - Cisco CCIP BGP 642-661 by Jeremy Cioara is more than just a certification prep tool; it’s a masterclass in internet routing. If you want to stop guessing what as-path prepend does and start feeling confident at the edge of your network, this is the series to watch.
Don't study for 642-661 – you can't take that exam. Instead, use Jeremy’s current ENCOR BGP content – same great teaching, up-to-date exam blueprint.
