If you locate a copy of the CBT.Nuggets.-.Cisco.CCIP.BGP..642-661 collection, you will typically find between 20 and 30 video modules. Here is a typical syllabus breakdown based on the original release:
Certification Status: The CCIP certification is defunct. If you are studying specifically for a modern certification (like CCNP Enterprise ENARSI or CCNP Service Provider SPCOR), this series does not cover 100% of the current blueprint.
Technical Value: Despite the exam retirement, the BGP concepts taught are timeless.
Back in the early-to-mid 2000s, BGP was the wizard’s art. You didn't just "learn BGP." You wrestled with it. The 642-661 exam was the gatekeeper for service providers and large enterprises. You needed to understand path attributes (Local Preference, AS_PATH, MED), route reflectors, confederations, and the haunting question: "Why is my BGP route not installing in the RIB?"
Most official Cisco press books read like tax law written by engineers. Enter Jeremy Cioara.
Jeremy didn't lecture. He performed. His voice—equal parts surfer dude, storyteller, and drill sergeant—turned dry protocol mechanics into campfire tales.
He would stand in front of a whiteboard (actual marker, actual board—no fancy graphics) and draw autonomous systems as clouds. Or circles. Sometimes as rival gangs of routers. He’d personify BGP attributes: "Local Preference is like giving your buddy a VIP pass. Weight? That’s the bouncer who really likes you."
The 642-661 series followed a golden arc:
Jeremy Cioara is arguably one of the most popular IT trainers in the industry. His teaching style in this series is the main draw for many students.
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.
The classroom lights dim. A single projector hums to life, and Jeremy Cioara’s familiar voice cuts through the quiet—equal parts clarity and contagious enthusiasm. The title slide blinks: "BGP Deep Dive — Cisco CCIP (642-661)." For many students this course begins as a tangle of autonomous systems, path attributes, and bewildering prefix permutations. For the curious few, it becomes a map of the internet’s spine.
Jeremy doesn’t start with dry definitions. He opens with a story: an ISP in the middle of a city-wide outage, routes flapping like a thousand nervous hands, customers calling, engineers juggling policies and peering agreements. He paints the stakes—why BGP matters beyond lab simulations—and the room leans in.
The course moves like a well-designed network. Foundational sessions establish the control plane: BGP neighbor relationships, session states, and finite-state machines. Jeremy uses crisp analogies—neighbors exchanging letters, each route signed with attributes that tell a story of preference and origin. Labs follow: you configure a neighbor, watch the session climb from Idle to Established, and feel the small victory as prefixes appear in the RIB.
Next comes path selection. Jeremy strips the algorithm down to its bones: local-preference like a home-town bias, AS-path as the travel history, MED as a gentle nudge, and weight as a private tie-breaker. He punctuates the lecture with practical heuristics—when to tweak local-preference, when to prepend AS paths, and how MEDs play across confederations. Real-world scenarios thread through the theory: multi-homed customers, transit vs. peering decisions, and graceful traffic engineering without breaking the global table.
Policy and filtering modules transform the abstract into craft. Route-maps, prefix-lists, and community tagging become the artisan’s tools. Jeremy guides learners through step-by-step labs: crafting a policy that rejects bogons, carving precise advertisements to a provider, or tagging routes so downstream peers behave predictably. He doesn’t hide the messiness—misapplied filters can orphan prefixes—and highlights troubleshooting patterns that turn panic into methodical diagnosis.
Advanced topics arrive like strategic maneuvers: route reflectors that simplify BGP topologies, confederations that mask complexity, and BGP attributes that enable sophisticated traffic engineering. Jeremy walks through failure modes—what happens when a route reflector suddenly drops, or when an implicit null disrupts expectations—and demonstrates mitigation strategies that have kept networks online under pressure.
Throughout, the course never forgets operational realities. Monitoring, logging, and graceful maintenance are woven into labs and lecture tales: a midnight firmware push, a misconfigured export that advertises internal routes, the quiet heroism of carefully staged changes. Jeremy’s tips—small habits honed in production—become lifelines: keep backups of configs, use clear community schemes, review AS-path filters before peering, and always test in a segmented lab. If you locate a copy of the CBT
By the final module, BGP stops being a collection of commands and becomes legible architecture. Students who once feared the Border Gateway Protocol now sketch diagrams with confident strokes—peering fabrics, route policies, and failure domains neatly annotated. The last lab simulates a multi-provider outage; the class collaborates, applies learned policies, and watches traffic shift as intended. When the simulated crisis resolves, applause is small but genuine. People feel accomplished.
The course closes not with finality but with momentum. Jeremy points to further reading, real-world RFCs, and community practices; he encourages curiosity and caution in equal measure. The trainees leave with more than a certification path—they carry a toolkit and a mindset: to design resilient policies, to troubleshoot calmly, and to remember that BGP is both art and engineering.
Outside the classroom, the internet keeps humming. Route announcements ripple across continents, ISPs negotiate peering at crowded exchanges, and somewhere a network engineer on call sleeps a little easier, knowing that behind those autonomous systems is a discipline learned well—one lecture, one lab, one careful configuration at a time.
In the world of IT certifications, there are legends, and then there is Jeremy Cioara
. If you were an aspiring network engineer in the mid-to-late 2000s, this specific course—Cisco CCIP BGP (642-661)—wasn't just a training video; it was a rite of passage. The Setting: The "Wild West" of the Core
The story begins with the CCIP (Cisco Certified Internetwork Professional), a certification that existed before Cisco consolidated its tracks. While the CCNA was the playground and the CCNP was the office, the CCIP was the "Service Provider’s realm." It was about the backbone of the internet.
At the heart of this was the 642-661 BGP exam. Border Gateway Protocol is notoriously complex—it’s the "protocol that runs the internet," full of esoteric attributes like Weight, Local Preference, and Multi-Exit Discriminators (MED). The Protagonist: Jeremy Cioara Jeremy Cioara
. In an era where most IT training was delivered by monotone instructors reading bullet points off a PowerPoint in a dark room, Jeremy was a lightning bolt.
He didn't just teach BGP; he lived it. He would draw frantically on a digital whiteboard, his voice rising with genuine excitement as he explained how a packet decides to traverse the globe. He was famous for his "coffee-fueled" energy and his ability to make a "routing loop" sound like a high-stakes thriller. The Plot: The "Aha!" Moment
The "story" of this course for many engineers follows a specific arc:
The Confusion: You start the course intimidated. BGP is abstract. You’re looking at AS numbers and peering sessions, feeling like you're trying to learn a new language.
The Cioara Effect: Jeremy starts talking. He uses analogies—comparing BGP attributes to a "neighborhood HOA" or a "travel agent." Suddenly, the "Path Selection Process" isn't a list of 13 rules to memorize; it's a logical story of how data finds its home.
The Lab: The climax usually happens in a home lab (likely GNS3 back then). You’d follow Jeremy’s lead, configure a neighbor relationship, and watch the routing table populate. When you successfully manipulated a route using a Route Map for the first time, it felt like magic. The Legacy
Today, the 642-661 exam is long retired, replaced by the CCNP Enterprise and Service Provider tracks. However, this specific CBT Nuggets series is often cited as the "Gold Standard" of networking education. It transformed a generation of "button-pushers" into true "architects" who understood the why behind the how.
For many, seeing that file name—CBT.Nuggets.-.Cisco.CCIP.BGP..642-661..with.Jeremy.Cioara—brings back memories of late nights, humming server fans, and the voice of a man who convinced them that networking was the coolest job in the world.
Are you looking to revisit these concepts for a current project, or are you hunting for a modern equivalent to this classic training? Technical Value: Despite the exam retirement, the BGP
The "CBT Nuggets Cisco CCIP BGP (642-661)" course, led by the legendary Jeremy Cioara
, is a hall-of-famer in the world of network engineering training.
Known for his high-energy whiteboard sessions and infectious enthusiasm, Jeremy didn't just teach the technical specs of the Border Gateway Protocol (BGP); he turned the "Protocol of the Internet" into a relatable, high-stakes drama. The Story: The Town of Autonomous Systems
Imagine a world where every "Autonomous System" (AS) is its own independent town. Some towns are massive metropolises (like Google or Amazon), while others are tiny hamlets (your local office).
The Introvert (iBGP): Inside each town, everyone talks freely. They share the gossip and the routes through Internal BGP (iBGP). But there's a catch—iBGP is shy. In Jeremy’s story, iBGP peers won't pass along information they learned from another iBGP friend unless you set up a "Route Reflector" (the town town-crier) or build a "Full Mesh" where everyone talks to everyone directly.
The Ambassador (eBGP): When a town wants to talk to its neighbors, it sends out an Ambassador: External BGP (eBGP). The eBGP Ambassador stands at the town gate (the Edge Router) and negotiates with the Ambassador next door.
The Influence (Route Manipulation): This is where Jeremy’s training shines. He explains that BGP is like a picky traveler. It doesn't just take the "shortest" path like a GPS; it takes the path it prefers based on the town's politics:
Weight: The "My Town, My Rules" attribute (Cisco-proprietary). If I like a route, I give it a heavy weight so I always use it.
Local Preference: The "Mayor’s Order." We tell everyone in our town which neighbor is our favorite for leaving the city.
AS Path: The "Travel Stamps." If a route has too many stamps (towns it passed through), it’s considered a long, tiring trip.
The Climax: The Internet Update: Jeremy would describe the chaos when a "Flapping Link" (a bridge that keeps breaking and being rebuilt) sends updates across the whole world. Without "Route Dampening," the entire planet’s routers would spend all day recalculating their maps, leading to the dreaded BGP "meltdown." Why This Training Matters
Even though the CCIP (Cisco Certified Internetwork Professional) track was retired and replaced by the CCNP Service Provider track, this specific BGP 642-661 course remains a favorite for engineers. It covers the fundamentals—like peering, attributes, and filtering—in a way that makes you feel like you're building the internet yourself.
If you're diving into this old-school nugget, expect to hear Jeremy shout, "Oh man, this is so cool!" at least once per video as he draws out the complex web that holds the world's data together. If you are looking for current BGP resources, I can:
