You can deploy BIG-IP Global Traffic Manager (GTM) on a network where BIG-IP Local Traffic Manager (LTM) is configured with one route domain and no overlapping IP addresses.
Perform these tasks to configure a route domain, and then to configure GTM to be able to monitor the LTM systems.
|Disabled||Use this option when you plan to manually add virtual servers to the system, or if your network uses multiple route domains. This is the default value.|
|Enabled||The system automatically adds virtual servers using the discovery feature.|
|Enabled (No Delete)||The system uses the discovery feature and does not delete any virtual servers that already exist.|
