This image shows a VNet (172.169.0.0/16) in the Japan East (Tokyo) region of Microsoft Azure connected with a VCN (192.168.1.0/24) in the Japan East (Tokyo) region of Oracle Cloud Infrastructure region using a private interconnection composed of Microsoft Azure ExpressRoute and Oracle Cloud Infrastructure FastConnect.

A VNet gateway on the Azure side and a dynamic routing gateway (DRG) on the Oracle Cloud side enable private connectivity between resources in Azure (a Linux VM attached to the 172.169.1.0/24 subnet in this example) and resources in Oracle Cloud Infrastructure (an autonomous database attached to the 192.168.1.128/25 subnet in this example).

The image also shows route tables and security lists in Oracle Cloud to regulate the flow of network traffic. An internet gateway allows traffic between the internet and the public subnet 192.169.1.0/25 in Oracle Cloud.
