This is where the "Cioara Effect" shines. He categorizes the infamous BGP attributes into a logical decision tree.
Jeremy teaches you the BGP Best Path Selection Algorithm using a mnemonic memory trick. You will learn how to influence traffic inbound (using Local Pref) vs. outbound (using MED and AS Path Prepending).
The course was not without drawbacks. Being video-based, it lacked the interactive labs of a simulator. Some topics (e.g., BGP communities) received less depth than in Cisco’s official documentation. However, as a supplement to hands-on practice and reading, it was outstanding. cbt nuggets cisco ccip bgp 642661 by jeremy cioara new
Today, the CCIP is obsolete, replaced by CCNP Service Provider. Yet Cioara’s BGP series remains a favorite among engineers studying BGP for real-world roles. His teaching philosophy—understand why, not just how—transcends any single certification.
Cioara consistently analogized BGP to human decision-making. For example: This is where the "Cioara Effect" shines
This narrative anchoring reduced rote memorization and increased conceptual retention.
Jeremy Cioara’s CBT Nuggets Cisco CCIP BGP (642661) is a practical, instructor-led course well suited for network engineers seeking hands-on BGP configuration and troubleshooting skills on Cisco platforms; best used alongside lab practice and vendor documentation.

Jeremy starts with the "why." He explains the difference between Interior Gateway Protocols (OSPF/EIGRP) and Exterior Gateway Protocols (BGP). You will learn about:
iBGP requires a full mesh (every router peers with every other router). In a service provider network, this is impossible. Jeremy walks you through:
Unlike slide-based courses, Cioara used a physical or digital whiteboard to draw ASes as houses, paths as roads, and attributes as traffic signs. He intentionally introduced broken configurations (e.g., IBGP full-mesh requirement) and then physically drew the fix (adding route reflectors). This "visual debugging" is supported by dual-coding theory (Paivio, 1986)—combining verbal and visual channels improves learning outcomes for complex protocols.
