Cloud Enterprise Network:CEN instances

Last Updated:Mar 15, 2024

Cloud Enterprise Network (CEN) instances are basic network resources that are used to manage interconnected networks. Transit routers are deployed on CEN instances. A CEN instance contains one or more transit routers. To establish network communication among network instances in the same region or different regions, you can create inter-region connections to connect transit routers in different regions. Before you can use transit routers to establish network communication, you must create a CEN instance.
