The static proximity method for GSLB uses an IP address-based static proximity database to determine the proximity between the client’s local DNS server and the GSLB sites. The NetScaler appliance responds with the IP address of a site that best matches the proximity criteria.
If two or more GSLB sites at different geographic locations serve the same content, the NetScaler appliance maintains a database of IP address ranges and uses the database for decisions about the GSLB sites to which to direct incoming client requests.
To configure GSLB for proximity with static proximity, you must first configure the basic GSLB set up and then configure static proximity.
First create two GSLB sites, local and remote. Then, for the local site, create a GSLB virtual server and GSLB services and bind the services to the virtual server. Then create ADNS services and bind the domain for which you are configuring GSLB to the GSLB virtual server at the local site. Finally, create a load balancing virtual server with the same virtual server IP address as the GSLB service.
For details on how to configure a basic GSLB setup, see Configuring Global Server Load Balancing (GSLB).
Once you have configured a basic GSLB setup, configure static proximity.
For details on how to configure the GSLB virtual server to use static proximity for load balancing, see Configuring Static Proximity.
