Thanks for the response. Unfortunately, I didn't find the info I am looking for in this article. I am trying to figure out how a DNS query that a user sends ends up on a BigIP DNS.
So, we have 2 BigIP DNSes and we're using Wide IPs for looking up a query once it gets there. But what's the path for that query getting to one of the BigIP DNS?
Client Local DNS (LDNS) -> DNS Root -> DNS TLD (.com) -> BIG-IP DNS servers (yourdomain.com)
Then, selection between the two BIG-IP DNS depend on the loadbalancing algorithm defined at GSLB level.
