Routing concepts

Many routing concepts apply to static routing. However without first understanding these basic concepts, it is difficult to understand the more complex dynamic routing.

This section includes:

• Routing in VDOMs
• Default route
• Adding a static route
• Routing table
• Building the routing table
• Static routing security
• Multipath routing and determining the best route
• Route priority
• Troubleshooting static routing

Routing in VDOMs

Routing on FortiGate units is configured per-VDOM. This means if VDOMs are enabled, you must enter a VDOM to do any routing configuration. This allows each VDOM to operate independently, with its own default routes and routing configuration.

In this guide, the procedures assume your FortiGate unit has VDOMs disabled. This is stated in the assumptions for the examples. If you have VDOMs enabled you will need to perform the following steps in addition to the procedure’s steps.

To route in VDOMs – web-based manager

Select the VDOM that you want to view or configure at the bottom of the main menu.

To route in VDOMs – CLI

Before following any CLI routing procedures with VDOMs enabled, enter the following commands. For this example, it is assumed you will be working in the root VDOM. Change root to the name of your selected VDOM

as needed.

config vdom edit root

Following these commands, you can enter any routing CLI commands as normal.
