Behavior of outbound DNS query from LTM behavior
We're having intermittent dns failures from our ltm to fqdn-defined resources. 4 name server IPs are confgured. Since the GUI provides an up/down order button, I presume ip1 is queried, then ip2 if no response, etc. down to ip4, instead of round robin through them. However, I can't find confirmation of this in an F5 kb. If ip1 does not respond, how long before ip2 is queried? Until the timeout, or some shorter interval? This is intermittent, so it's classic needle in the haystack.Is it possible to monitor stats for dns query, response, and failure over time?Solved556Views1like2Comments
