I have inherited an f5 pair that is (in theory) an authoritative-only name server. it has a pool of three dns servers it passes queries to.
The first lookup using the f5 as the dns server has the authoritative bit set. However, subsequent queries (cache hit) do not, until the ttl time has elapsed. In other words, it acts as a standard dns caching server that sets authoritative when it has to query an authoritative server for an answer.
Is there a way to set up the F5 with this configuration to always answer authoritative?
bigip version 18.104.22.168
udp listener with dns profile name: "authoritative_dns"
