Overview: Integrating GTM with other BIG-IP systems on a network
You can add BIG-IP Global Traffic Manager (GTM) systems to a network in which BIG-IP Local Traffic Manager (LTM) systems and BIG-IP Link Controller systems are already present. This expands your load balancing and traffic management capabilities beyond the local area network. For this implementation to be successful, you must authorize communications between the systems.
About iQuery and communications between BIG-IP systems
The gtmd agent on BIG-IP Global Traffic Manager (GTM) uses the iQuery protocol to communicate with the local big3d agent, and the big3d agents installed on other BIG-IP systems. The gtmd agent monitors both the availability of the BIG-IP systems, and the integrity of the network paths between the systems that host a domain and the local DNS servers that attempt to connect to that domain.

Task summary
To authorize communications between BIG-IP systems, perform the following tasks on the BIG-IP GTM system that you are adding to the network.
