I am trying to get a thorough understanding of what does happen when a switch is connected to a portfast port on another switch that is part of a stable STP network in case of: 1- the port has no bpduguard. 2- the port has the bpduguard enabled. However, how is that better than reverting the port back to STP?

In recent years, Meta’s data management systems have evolved into a composable architecture that creates interoperability, promotes reusability, and improves engineering efficiency. Over time, these divergent systems created a fragmented data environment with little reuse across systems, which eventually slowed our engineering innovation.
