: Mastering the path selection process taught by Jeremy is a prerequisite for the CCIE lab.
Jeremy doesn't just show you commands; he builds topologies. The training encourages you to follow along in GNS3, VIRL, or physical gear. By the time you reach the sessions on Attribute Manipulation : Mastering the path selection process taught by
Jeremy does not read slides. He draws. In the 642-661 series, he famously uses the whiteboard to turn BGP into a story about "The Postal Service" or "Airlines flying between cities." By the time you reach the sessions on
Even though the track was retired and replaced by the CCNP Service Provider track, this specific BGP 642-661 course remains a favorite for engineers. It covers the fundamentals—like peering , attributes , and filtering —in a way that makes you feel like you're building the internet yourself. It covers the fundamentals—like peering , attributes ,
Throughout, the course never forgets operational realities. Monitoring, logging, and graceful maintenance are woven into labs and lecture tales: a midnight firmware push, a misconfigured export that advertises internal routes, the quiet heroism of carefully staged changes. Jeremy’s tips—small habits honed in production—become lifelines: keep backups of configs, use clear community schemes, review AS-path filters before peering, and always test in a segmented lab.
