Which settings need to be applied for traffic routing between multiple VDOMs?

To enable traffic routing between multiple Virtual Domains (VDOMs) in a Fortinet device, establishing inter-VDOM links with the appropriate network policies is crucial. These inter-VDOM links facilitate direct communication between VDOMs, allowing for efficient data transfer without needing external interfaces or intermediary devices.

By configuring these links, you can define specific policies to control the flow of traffic between VDOMs, such as setting security policies or firewall rules. This helps maintain security while also ensuring that routing is done in a structured manner. Inter-VDOM links create a logical connection that allows VDOMs to communicate seamlessly, thus simplifying the management of resources that span multiple domains.

In contrast, other options may imply more complex or indirect methods of routing between VDOMs. The need for a router specifically to forward data or relying solely on management VDOM settings does not align with the streamlined process that inter-VDOM links provide, which is designed explicitly for inter-VDOM communication.
