: Understanding autonomous systems (AS), establishing iBGP and eBGP neighbor relationships via TCP port 179, and managing the BGP state machine.

While modern engineers must also learn concepts like automated network programmability, EVPN-VXLAN, and Segment Routing, Cioara's deep dive into BGP fundamentals provides an evergreen foundation. Network professionals still hunt down this legacy CBT Nuggets series to gain a rock-solid, conceptual understanding of the internet's core protocol. Final Thoughts

The course does not cover MP-BGP (Multiprotocol BGP) for IPv6 or VPNs in extensive depth, nor does it cover BGP Flowspec or Segment Routing . However, for pure BGP fundamentals and internet routing, it remains a masterclass.

Used to determine the preferred exit point from an Autonomous System.

Evaluates how the route was injected (IGP over EGP). This specific series is often cited as the

It is more than just an exam prep video; it is a masterclass in thinking like a network engineer, taught by one of the industry's most beloved instructors. If you want to build a solid, intuitive grasp of BGP that you can apply in real-world situations, this training remains an invaluable resource.
