You can deploy BIG-IP Global Traffic Manager (GTM) on a network where BIG-IP Local Traffic Manager (LTM) systems are configured with multiple route domains and overlapping IP addresses.
The following figure shows BIG-IP GTM deployed in a network with multiple BIG-IP Local Traffic Manager (LTM) systems configured with the default route domain (zero), and two additional route domains. BIG-IP GTM can monitor the Application1 and Application2 servers that have overlapping IP addresses and reside in different route domains. The firewalls perform the required address translation between the BIG-IP GTM and BIG-IP LTM addresses; you must configure the firewalls to segment traffic and avoid improperly routing packets between route domain 1 and route domain 2.
Before BIG-IP GTM can gather status and statistics for the virtual servers hosted on BIG-IP LTM systems on your network that are configured with route domains, you must configure the following on each BIG-IP LTM that handles traffic for route domains:
Additionally, on BIG-IP GTM you must:
Perform the following tasks to configure BIG-IP GTM to monitor BIG-IP LTM systems with route domains.
|Inherit from Data Center||By default, a server inherits the Prober pool assigned to the data center in which the server resides.|
|Prober pool name||Select the Prober pool that contains the BIG-IP systems that you want to perform monitor probes of this server.|
