DNS - Service Port and Monitoring for Generic Host
Hi all,
I have a couple of questions. given the below setups on a GTM/DNS:
Scenario 1: FQDN - Pool - Pool Member 1 (Enabled), Pool Member 2 (Enabled). Both Pool members are generic hosts. No health check monitor. Global Availability.
In the above scenario, will Global Availability never function, because no health monitor is checked? Will custom service ports and custom monitors be required in order to successfully fail over traffic and responses from Member 1 and Member 2?
Scenario 2: FQDN - Pool - Pool Member 1 (Enabled), Pool Member 2 (Disabled). Both Pool members are generic hosts. No health check monitor.
In the above scenario 2, if I want the F5 DNS to practically act like a traditional DNS server, would the above config suffice? Would the service port configured under the pool members have zero relevance in this case? Would Pool Member 1 be up and green at all times, regardless of the state of the server and whether it's up or down?
Thanks
