If you are currently preparing for a networking role or exam, let me know how I can help. I can outline a for you, break down the BGP path selection algorithm step-by-step, or explain specific troubleshooting commands . Which of those options would help you most right now? Share public link
Cisco retired the 642-661 exam in 2012. The CCIP certification is no longer available. So why would anyone watch a retired training series today?

Exploring the CBT Nuggets Cisco CCIP BGP 642-661 Course by Jeremy Cioara
The way Cioara explains BGP path selection—breaking it down step by step, using memorable analogies, and connecting each attribute to real-world behavior—isn’t something that goes out of date. That pedagogical approach remains as effective today as it was when the videos were first recorded.
The course systematically contrasts the behavior of BGP running within an enterprise system (iBGP) versus BGP extending to outside carriers (eBGP). Cioara walks students through the , which prevents loops by mandating that a route learned from an iBGP peer cannot be advertised to another iBGP peer. This introduces advanced structural remedies like Route Reflectors and Confederations . 2. The BGP Best Path Selection Algorithm
(Network command or redistribution) AS-Path Length (Shortest path vector) Origin Code (IGP over EGP/Incomplete)
Manually configuring BGP neighbors and verifying routing tables.
A course is useless without practice. The new CBT Nuggets series integrates seamlessly with (their in-browser virtual environment). You don't need to own a physical 7200-series router. Jeremy provides downloadable topology maps (usually a 4-router cluster) so you can follow along.
