Several parameters must be configured for GSLB clustering to operate efficiently. These settings reflect general DNS best practices and ensure proper distribution of traffic.
This is the time to live setting, which reduces the DNS resolver cache to ensure even distribution across the load balancers in the cluster. This can also be set within the FQDN settings.
This setting ensures that GSLB will not send the same response back to the client for the specified amount of time.
