The DNS HM (Health Monitoring) Probe issue typically refers to problems encountered when health monitoring systems use DNS probes to check the availability or performance of DNS services.

The DNS is configured with a pool and we are performing HM of the pool member under the GSLB TAB.

Now as i understand in order to begin probing , we need to configure the source IP that will be used for probing .

This is done by creating a server under GSLB and while configuring the server under devices i need to add the self IP without route domain.

now since i have multiple route domain how can i make this working.
