The modern CCNP and CCIE exams focus heavily on automation (Python, Ansible, YANG) and overlay technologies (VXLAN, SD-WAN). However, when an SD-WAN tunnel fails, the underlay routing still relies on BGP. When a cloud provider gives you a private ASN, you need to know MED and Local Pref.

If you are a junior engineer frustrated with BGP, find a copy of this course. The graphics are dated, the router beeps are nostalgic, but the logic is timeless. Jeremy doesn't teach you to pass a test; he teaches you to be a routing detective. CBT Nuggets - Cisco CCIP BGP 642-661 By Jeremy Cioara

Jeremy used the analogy of a rumor in a high school. He would draw three routers in a triangle, explaining that if Router A tells Router B a secret, Router B is not allowed to tell Router C unless there is a direct connection (full mesh) or a route reflector. He then dedicated a full 45-minute lab to configuring a —solving the problem with dramatic flair. 3. Communities and Route Filtering Before BGP communities, route filtering was a mess of prefix-lists. Jeremy showed how tagging a route with a community (like 100:10 for "Customer A") allowed for scalable outbound filtering. The lab for this episode was famous: He created an ISP scenario with five customers, used route-maps to set communities as routes came in, and then used ip community-list to advertise only specific blocks back out.
