Master BGP with Jeremy Cioara: A Deep Dive into the CBT Nuggets Cisco CCIP 642-661 Course
For many network engineers, the "holy grail" of routing protocols is BGP (Border Gateway Protocol). It is the language of the internet, the protocol that connects autonomous systems, and arguably the most complex topic in the Cisco certification track. If you are hunting for the CBT Nuggets Cisco CCIP BGP 642-661 course featuring Jeremy Cioara, you are looking for what many consider the gold standard of networking education.
While the CCIP (Cisco Certified Internetwork Professional) certification has since been retired and evolved into the CCNP Service Provider track, the foundational knowledge found in Jeremy Cioara’s 642-661 "work" remains timeless. Why Jeremy Cioara’s BGP Training is Legendary
Jeremy Cioara is known in the IT world for his infectious energy and his ability to make incredibly dry technical concepts—like BGP attributes and peer groups—feel like an exciting adventure. In the 642-661 series, Jeremy moves beyond the basics of "how to type the commands" and dives deep into the "why" behind the protocol. What makes this specific CBT Nuggets series stand out:
The "Jeremy" Factor: His whiteboard-style teaching turns abstract routing tables into visual maps.
Real-World Scenarios: He doesn't just teach for the exam; he teaches for the production environment.
Micro-Learning: CBT Nuggets pioneered the short, digestible video format, allowing you to master complex BGP path selection one nugget at a time. Key Topics Covered in the 642-661 Series
The BGP 642-661 exam was a core requirement for the CCIP. To pass it (and to understand BGP in the real world), Jeremy guides you through several critical domains:
1. BGP Peerings and AdjacenciesUnderstanding the difference between EBGP (External) and IBGP (Internal) is the starting point. Jeremy explains the "Split Horizon" rule in IBGP and why tools like Route Reflectors and Confederations are necessary to scale a network.
2. The BGP Best Path Selection ProcessThis is the heart of the course. Jeremy breaks down the 13-step decision process that BGP uses to choose a route. You’ll learn how to manipulate traffic using: Weight: (Cisco proprietary) Local Preference: For outbound traffic control. AS-Path Prepending: To influence inbound traffic. cbt nuggets cisco ccip bgp 642661 by jeremy cioara work
MED (Multi-Exit Discriminator): For suggesting paths to neighbor ASs.
3. Policy Control and FilteringBGP is all about policy. The course covers Prefix Lists, Route Maps, and AS-Path Filters (using Regular Expressions), giving you total control over which routes enter and exit your network.
4. Transit AS and Customer ConnectivityYou’ll learn how a Service Provider handles "transit" traffic, including how to connect multi-homed customers who want redundancy across two different ISPs. Is the 642-661 Content Still Relevant Today?
Even though Cisco has updated its exam numbers (moving toward the 350-401 ENCOR and 300-410 ENARSI), the BGP 642-661 material is still 95% relevant. BGP hasn't changed fundamentally in decades. If you can master the concepts Jeremy teaches in this legacy course, you will be ahead of the curve for any modern Cisco Enterprise or Service Provider exam. How to Put This Knowledge to Work
To truly benefit from "Jeremy Cioara's work," you cannot just watch the videos. You must lab.
GNS3 or CML: Use these to recreate the topologies Jeremy draws on his screen.
Focus on Troubleshooting: Don't just follow the "happy path." Break the neighbor relationship and see how the BGP table reacts. Conclusion
The CBT Nuggets Cisco CCIP BGP 642-661 course is more than just an exam prep tool; it’s a masterclass in internet routing. Jeremy Cioara’s unique teaching style removes the intimidation factor from BGP, making it accessible for engineers at any level. Whether you are aiming for a modern CCNP or just need to fix a routing loop at work, this series remains a premier resource in the networking community.
Jeremy Cioara's Cisco CCIP BGP 642-661 course focuses on practical service provider scenarios, specifically teaching how to initiate and manage BGP sessions with carriers. The training also emphasizes high-energy instruction to simplify complex, real-world protocol applications, including route redundancy and BGP best path manipulation.

The CBT Nuggets Cisco CCIP BGP 642-661 course by Jeremy Cioara
was a classic training series designed to prepare network engineers for the Border Gateway Protocol (BGP) portion of the now-retired Cisco Certified Internetwork Professional (CCIP) certification. Key Course Details
Instructor: Jeremy Cioara, known for his high-energy and "infectious enthusiasm".
Focus: Mastering BGP, the "routing protocol of the internet," and its configuration on Cisco hardware.
Target Audience: Network engineers or IT professionals with at least one year of infrastructure experience. Core Concepts: Fundamental BGP configurations (forming neighbors). Advanced path manipulation and data transit control. Connecting to multiple ISPs for load balancing or backup. Legacy and Current Status
While the specific 642-661 exam is no longer active, the concepts Jeremy taught remain foundational for modern certifications like the CCNP Enterprise (ENARSI) or specialized BGP training. CBT Nuggets has since released updated versions, such as their Border Gateway Protocol (BGP) Online Training, which covers modern additions like SD-WAN integration. 📺 Watch to Get Started

For a deeper look at the '5-step process' Jeremy uses to explain BGP implementation: 05:32
“Set up two ASs (AS 100 and AS 200). Configure EBGP between R1 and R2. Manipulate local preference so that AS 200 prefers a backup link for incoming traffic from AS 100 without changing MED.” A Typical Lab from the Course:

Even today, in forums like r/ccie, r/networking, and TechExams.net, you’ll find old threads praising this specific course. Common sentiments include:
If you do obtain Jeremy’s 642-661 series, here’s how to leverage it today:
Even though you cannot take exam 642-661 today, the BGP concepts Jeremy taught are more critical than ever:
Learning BGP the “Jeremy Cioara way”—through visualization, storytelling, and hands-on CLI—gives you mental models that translate directly to modern networks.
In the golden era of Cisco certification—roughly the mid-to-late 2000s—the path to becoming a true internet routing expert went through the Cisco Certified Internetwork Professional (CCIP) certification. Among its most feared and respected exams was 642-661: Configuring BGP on Cisco Routers (BGP).
And when network engineers of that generation talk about learning Border Gateway Protocol (BGP), one name towers above the rest: Jeremy Cioara, and his legendary CBT Nuggets video course for CCIP BGP 642-661.
Even today, almost two decades later, the phrase “cbt nuggets cisco ccip bgp 642661 by jeremy cioara work” still surfaces in forums, study groups, and old hard drives. Why? Because that course wasn’t just a test-prep tool—it was a masterclass in making the internet’s most complex routing protocol feel human.
