It looks like you’re referring to a classic piece of training material from CBT Nuggets: the Cisco CCIP BGP (642-661) course taught by Jeremy Cioara.

While I can’t reproduce the actual video content or copyrighted transcripts from the course, I can certainly write a descriptive and nostalgic piece about what that training represented, its structure, and why it became legendary among network engineers studying Border Gateway Protocol (BGP).

Here’s a piece capturing the essence of that training:

The Jeremy Cioara Method

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:

  1. The Why – Why do we need BGP when we have OSPF? (Spoiler: scale and policy).
  2. The Handshake – eBGP vs iBGP, loopback peering, and the dreaded "TTL=1" trap.
  3. The Brain – Path selection step-by-step. Jeremy’s mnemonic for the 13-step BGP best-path algorithm became folklore.
  4. The Madness – Route reflectors, peer groups, and soft reconfiguration.
  5. The Real World – Influencing traffic inbound/outbound with AS_PATH prepend and MED.

The Context: Why 642-661 Mattered

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.

Module 6: Peerings & Security

  • MD5 authentication
  • TTL Security (GTSM)
  • Maximum prefix limits

Instructor Profile: Jeremy Cioara

Jeremy Cioara is one of CBT Nuggets’ most celebrated instructors, known for:

  • High energy and engaging delivery.
  • Simplifying complex topics with analogies and whiteboard drawings.
  • Strong focus on understanding rather than rote memorization.
  • Practical lab demonstrations alongside theory.

His BGP course is widely regarded as a classic for learning BGP from the ground up.

3. Mnemonics for the Path Selection Algorithm

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.

Narrative: CBT.Nuggets - Cisco CCIP BGP (642-661) with Jeremy Cioara — Training

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. It looks like you’re referring to a classic

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.

This specific CBT Nuggets training series, led by Jeremy Cioara

, focuses on the BGP (Border Gateway Protocol) portion of the legacy Cisco CCIP (Cisco Certified Internetwork Professional) certification.

While the CCIP certification has since been retired and replaced by the CCNP Service Provider track, this course remains a popular resource for its clear explanation of BGP fundamentals. According to the Introductory Nugget, the series is designed for engineers working with service providers who need a deep dive into BGP configuration and theory. Key Topics Covered

BGP Basics: Understanding Autonomous Systems (AS), eBGP vs. iBGP, and peering relationships. The Jeremy Cioara Method Jeremy didn't lecture

Path Selection: Detailed look at BGP attributes like Weight, Local Preference, AS-Path, and MED.

Policy Control: Using prefix lists, route maps, and community strings to control traffic flow.

Scalability: Implementing Route Reflectors and Confederations to manage large-scale BGP networks.
