irule for LTM: provide "no error" or reject for AAAA DNS queries

Hi All,     I found the irule below to provide "no error" response for AAAA DNS queries but it seems this is for GTM only. Anyone knows what is the irule for LTM? My DNS servers are load balance...

Hi,

 

 

You must have a GTM license to use the DNS_ events or DNS:: commands. With LTM, you'd need to do binary parsing of the requests. Nat added an example iRule to the Codeshare which decodes and logs details on DNS requests and responses. Maybe you could adapt that for your scenario?
