GSLB

I am trying to implement a GSLB deployment with two data centers geographically located in different locations.\

How is the DNS configuration managed so that requests that reach the External DNS are taken to the A10 for resolution?

Has anyone already done this type of deployment before?

This is the topology I'm trying to deploy.

    The most common approach I see is using the sub-domain delegation and CNAME records as depicted in the PDF provided. This is also known as "server mode".

    There is also "proxy mode" where the A10 VIP sits in front of the backend DNS servers to provide load balancing functions as well as DNS Security for the real servers.

    Additional details are also available within the GSLB guide on the Support Portal.
