BGP design in CloudNetX scenarios is rarely about memorizing attributes and more about understanding peering intent, route control, and operational stability. This episode explains BGP as a mechanism for expressing routing policy between networks, where the primary objective is to control what routes are exchanged, which routes are preferred, and how failures are handled without destabilizing connectivity. The first paragraph focuses on peering intent—transit, peering, private connectivity, or cloud interconnect—because intent determines what should be advertised, what should be accepted, and what risk controls must exist. It also introduces stability concepts such as controlling route scope, avoiding unnecessary churn, and ensuring changes are deliberate and reversible, since BGP problems can create broad impact quickly.
