GTM topology on internal network
Hi,
I plan on doing proximity routing internally and thought of doing that via GTM. I configured topology on GTM and realized that the query originated from LDNS and not the actual client (new learning for me). Next step, I modified the topology according to our regional dns infrastructure and did some basic testing which worked fine. Now comes the real problem. We have Anycast deployed across company network for dns server. All client machines have primary dns server with Anycast IP which should be one of the closest dns server. The problem is that the Anycast is not working as expected, and the client is routed to only one DNS server. This breaks the topology configuration on GTM. If I change the DNS server to specific one, it works fine as expected. We are looking at the routing config but would like to know if there is any way to have client query the GTM directly? Is there any other to achieve this? or Can we have client make iterative query?
Thanks in advance.
