What is the role of BGP dynamic routing in the connection between an Azure VNet and OCI VCN?

Border Gateway Protocol (BGP) is a dynamic routing protocol used in the OCI-Azure Interconnect to

automatically determine the optimal path for data between an Azure Virtual Network (VNet) and an OCI

Virtual Cloud Network (VCN). Unlike static routing (Option A), BGP adapts to network changes,

ensuring efficient and reliable connectivity. It doesn’t establish the connection itself (Option B) or

manage security rules (Option C)—those are handled by FastConnect/ExpressRoute and security lists,

respectively. Oracle’s networking documentation for multicloud interconnects confirms BGP’s role in

route optimization.
