Placing BIG-IP DNS in front of a Pool of DNS Servers
The F5 DNS server was positioned in front of a pool of Microsoft DNS servers. If the record is wideip, F5 DNS will answer to the query; else, the inquiry will be forwarded to Microsoft DNS server. Before the integration, we tested the wideip by setting the F5 listener (10.1.226.249) as the user's primary DNS server. It responded as predicted and dropped the query if the non-wideip. Following the test, we incorporated the Microsoft DNS servers (10.3.2.2 and 10.3.2.4) as nodes >> Pool>> and connected this pool to the F5 listener (10.2.226.249).If a wideip query is made at this time, it will typically be forwarded to Microsoft DNS, and if that fails, it will resolve locally. The first three attempts at nslookup will be dropped, and the name will be resolved. How do I prioritise wideip queries to be resolved by F5 DNS rather than sending them primarily to Microsoft DNS servers?Solved1.4KViews0likes7Comments
