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.
The 642-661 exam’s biggest killer was . Most students memorized the order. Jeremy drilled it differently: he would change one attribute at a time, run show ip bgp , and ask “Which path wins and why?” repeatedly until it became instinct. His coverage of Multiprotocol BGP for MPLS VPNs was especially rare for video training at the time—most books glossed over it, but Jeremy simulated a full VRF configuration. cbt nuggets cisco ccip bgp 642661 by jeremy cioara work
While Cisco has since retired the CCIP designation—evolving its curriculum into the CCNP Enterprise and CCNP Service Provider tracks—the fundamental mechanics of BGP have remained unchanged. The protocol still runs the global internet. The Jeremy Cioara Factor: Why This Training Worked Jeremy famously used a simple whiteboard and colored

: Using prefix lists, route maps, and community strings to control traffic flow and prevent routing loops. Troubleshooting
Network engineering courses can easily become dry, bogged down by RFC definitions and endless hexadecimal notation. Jeremy Cioara revolutionized IT video training by injecting high energy, real-world analogies, and hands-on whiteboarding into the CBT Nuggets platform. 1. High-Energy Engagement
