Don't just follow the "happy path." Break the neighbor relationship and see how the BGP table reacts. Conclusion
While Cisco retired the specific 642-661 exam in July 2012, replacing the CCIP track with the certification, the foundational knowledge in Jeremy’s course remains a cornerstone for network engineers today.

Jeremy had a gift for simplifying complex BGP concepts. For example, he famously explained the BGP path selection process as a “ranking system” comparing it to choosing a route to a vacation destination—shortest path, most reliable carrier, known friends (AS Path), etc. Don't just follow the "happy path
Jeremy Cioara didn’t just teach BGP—he demystified it. He turned a protocol feared for its complexity into a logical, even enjoyable, puzzle. If you ever get a chance to watch that old course, do it. Not for exam braindumps or quick answers, but to see a master teacher at the peak of his powers. For example, he famously explained the BGP path
Mastering BGP , the "routing protocol of the internet," and its configuration on Cisco hardware.
These metaphors stuck long after the exam.
Jeremy famously used a simple whiteboard and colored markers to draw live, evolving topology diagrams. He would act out routing decisions as if he were a packet, walking through AS_PATH prepending or LOCAL_PREF decisions. His catchphrases—”BGP is a path-vector protocol that lives in the control plane”—became mental anchors.
