The main competitor to CBT Nuggets. Their "Advanced BGP" course (by Brian McGahan) is arguably more detailed than the old 642-661 series.
In the mid-2000s, if you were pursuing the now-retired Cisco Certified Internetwork Professional (CCIP) certification or studying for the legendary CCIE Routing and Switching lab, one exam code struck both excitement and fear into the hearts of network engineers: 642-661 BGP (Border Gateway Protocol). This exam, officially titled "Configuring BGP on Cisco Routers," was the gold standard for proving your mastery of the internet’s core routing protocol.
Alongside official Cisco press books, one training series stood head and shoulders above the rest: CBT Nuggets. Their high-energy, whiteboard-heavy video training for the 642-661 BGP exam became a cult classic. Even today, searches for "cbt nuggets cisco ccip bgp 642-661 download" persist—a testament to the timeless quality of that content.
But here is the critical reality check: The 642-661 exam was retired over a decade ago, replaced by exams like 300-101 ROUTE and later 350-401 ENCOR. Downloading a pirated copy of that old CBT Nuggets series is not only illegal but also technically obsolete.
This article will accomplish three things:
Watching videos is passive. To truly master the topics from the 642-661 exam, you need to build a lab. Here is how to do it for free or cheap.
Searching for a "cbt nuggets cisco ccip bgp 642-661 download" is a dead-end road paved with malware and legal risk. The gold you are looking for isn't a file; it's the skill set.
To get that skill set:
The legacy of the CCIP 642-661 lives on in every BGP route that traverses the internet today. Honor that legacy by learning the right way—legally, hands-on, and relentlessly.

The Cisco CCIP BGP 642-661 exam was a core component of the legacy Cisco Certified Internetwork Professional (CCIP) certification, which has since been retired and superseded by the CCNP Service Provider track. The CBT Nuggets series for this exam, featuring trainer Jeremy Cioara, remains a popular archival resource for mastering the foundational and advanced mechanics of the Border Gateway Protocol (BGP). Overview of CBT Nuggets BGP 642-661
While the specific 642-661 exam is no longer active, the training content remains technically relevant for network engineers because the core principles of BGP have not changed. The series is designed for individuals working in Service Provider environments who need to manage large-scale routing. Trainer: Jeremy Cioara.
Focus: Practical implementation of BGP rather than just passing a test. Key Learning Outcomes:
Configuring internal BGP (iBGP) and external BGP (eBGP) neighbor relationships.
Manipulating path selection using attributes like Local Preference, Weight, and AS-Path. Scaling networks using Route Reflectors and Confederations.
Managing traffic via prefix lists, route maps, and community strings. Core Exam & Course Topics
The training covers the following technical domains, which were the primary pillars of the 642-661 curriculum: Introductory Nugget: Cisco CCIP BGP 642-661
The fluorescent lights of the server room hummed a low, mocking B-flat as Elias stared at the console. He was a junior network engineer at a Tier-2 ISP, and for the last three hours, he’d been drowning in a "routing loop from hell." cbt nuggets cisco ccip bgp 642-661 download
His mentor, a grizzled veteran named Marcus who smelled faintly of stale coffee and solder, leaned over his shoulder. "BGP isn't just a protocol, Elias. It's the duct tape holding the internet together. If you don't respect the attributes, it’ll bite you."
Marcus handed him a weathered USB drive. "I did my CCIP back in the day. This is the old Cisco 642-661 course from CBT Nuggets. It’s classic stuff—Jeremy Cioara. It’s technically retired, but the way he explains BGP peering and route reflectors? It’s legendary. Watch it tonight."
That evening, Elias cleared his desk. He didn't just "download" the information; he absorbed it. On the screen, Jeremy’s energetic whiteboarding turned the abstract mess of Autonomous Systems into a digital neighborhood. Elias watched the videos on IBGP vs. EBGP, the Next-Hop-Self rule, and the intricate dance of the BGP Best Path Selection algorithm.
The next morning, Elias didn't hesitate. He sat back at the console, mapped out the Local Preference values, and adjusted the MED (Multi-Exit Discriminator) to steer the inbound traffic properly.
With one final clear ip bgp * soft, the routing table settled. The latency spikes vanished. The "Request Timed Out" messages transformed into steady, beautiful "64 bytes from..." replies.
He had transitioned from someone who just typed commands to someone who understood the flow. The old 642-661 exam might have been replaced by newer certifications, but the foundational logic he learned that night was timeless.
