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:

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.

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 642-661 exam required memorizing BGP’s best-path selection algorithm (often listed as 16 steps). Jeremy turned it into a sing-song acronym: "We Love Oranges AS Oranges Mean Pure Refreshment" (Weight, Local Pref, Originate, AS-Path, Origin, MED, etc.). Every student who took that course still whispers that phrase when troubleshooting route selection today.

Jeremy Cioara’s CCIP BGP (642-661) course is a masterclass in BGP fundamentals that has stood the test of time. While the exam is gone, the training is still an outstanding resource for any network engineer who wants to truly understand how BGP selects paths, filters routes, and scales in a service provider environment. Pair it with modern Cisco documentation and lab practice for best results today.

This training course, CBT Nuggets: Cisco CCIP BGP (642-661) with Jeremy Cioara, is a classic deep-dive into the Border Gateway Protocol (BGP), specifically tailored for the legacy Cisco Certified Internetwork Professional (CCIP) certification.

While the 642-661 exam has since been retired by Cisco, the fundamental BGP concepts taught by Jeremy Cioara remain highly relevant for modern certifications like the CCNP Enterprise (ENARSI). Course Overview

Jeremy Cioara uses his signature high-energy, whiteboard-driven style to break down one of the internet's most complex protocols. The course covers:

BGP Fundamentals: Understanding how the "Protocol of the Internet" scales and functions.

Neighbor Relationships: Configuring Internal BGP (iBGP) and External BGP (eBGP) peering.

The BGP Best Path Selection Process: A step-by-step look at how BGP chooses routes using attributes like Weight, Local Preference, AS-Path, and MED.

Policy Control: Using Route Maps, Prefix Lists, and Community strings to manipulate traffic flow.

Scalability: Implementing Route Reflectors and Confederations for large-scale service provider environments. Key Highlights

Practical Lab Scenarios: The training focuses on real-world configuration and troubleshooting on Cisco routers.

Conceptual Clarity: Simplifies "Transit AS" concepts and how BGP interacts with IGPs like OSPF or EIGRP.

Legacy Value: Even though the CCIP track was replaced by the CCNP Service Provider and later the CCNP Enterprise, this specific series is often cited by network engineers as one of the best "foundational" explanations of BGP ever recorded.

Master BGP with Jeremy Cioara: A Guide to the CBT Nuggets Cisco CCIP 642-661 Training

The CBT Nuggets Cisco CCIP BGP 642-661 training, led by the legendary Jeremy Cioara, remains one of the most iconic and effective resources for mastering the Border Gateway Protocol (BGP). While the specific 642-661 exam has been retired as part of Cisco's certification evolution, the fundamental BGP concepts taught in this course continue to be the backbone of modern internet routing and service provider networks. Why This Training Stands Out

Jeremy Cioara is renowned for his high-energy, "edutainment" style. He has a unique ability to take incredibly dense, technical topics—like BGP attributes and route reflectors—and turn them into digestible, whiteboard-driven lessons. For many engineers, this course served as the "aha!" moment for understanding how the global internet actually functions. Core Curriculum Highlights

The training covers the essential pillars of BGP that every Network Engineer must master:

BGP Fundamentals: Understanding the difference between Internal BGP (iBGP) and External BGP (eBGP), and why BGP is classified as a path-vector protocol rather than a standard distance-vector or link-state protocol.

The BGP Best Path Selection Process: Jeremy breaks down the complex 13-step tie-breaking algorithm, focusing on critical attributes like Weight, Local Preference, AS_Path, and MED (Multi-Exit Discriminator).

Policy Control & Manipulation: Learning how to use Route Maps, Prefix Lists, and Community strings to influence traffic entering and leaving your autonomous system.

Scalability Mechanisms: Deep dives into Route Reflectors and Confederations, which are essential for managing large iBGP meshes without requiring a full-mesh topology.

Connecting to the Internet: Practical scenarios for multi-homing, where a company connects to two or more ISPs to ensure redundancy and optimized path selection. Relevance in Today’s Networking Landscape

Even though Cisco shifted from the CCIP (Cisco Certified Internetwork Professional) to the CCNP Enterprise and Service Provider tracks, BGP has not changed. The logic you learn in the 642-661 training applies directly to:

CCNP Enterprise (ENARSI 300-410): BGP remains a massive portion of this advanced routing exam.

CCIE Enterprise Infrastructure: Mastering the path selection process taught by Jeremy is a prerequisite for the CCIE lab. Jeremy didn't lecture

Cloud Connectivity: Technologies like AWS Direct Connect and Azure ExpressRoute rely heavily on BGP for hybrid cloud integration. Is It Still Worth Watching?

Absolutely. While you should supplement this with updated materials regarding IPv6 and BGP monitoring (like BGP Stream), Jeremy Cioara’s foundational teaching on BGP peering, state machines, and attribute manipulation is timeless. If you are struggling with the "why" behind BGP configurations, this CBT Nuggets series is often the best place to start.

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 Supplement with modern resources if you:

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:

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.

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.
