Help me understand GTM Load Balancing Algorithm and how Topology Records and Topology Regions play i
We have two Topology Regions: Internal space (10.0.0.0/8) and External space (public facing IPs).
The GTM is configured with two listeners, one internal-facing the other external-facing
The GTM is configured with two Topology Records defined in the following order:
Order LDNS Request Src Destination
1 10.0.0.0/8 Region is Internal space
2 0.0.0.0/0 Region is External space
The way I understand this is that if the LDNS request source originates from our internal private IP space, then the GTM responds with a pool member in the Internal IP space, else it responds with the pool member in our External IP space.
Now, we have a set of Windows DNS servers in our DMZ space that delegates queries to our GTMs external listeners. My question comes when we have a WIDE IP configured only with only an Internal_space pool member which is being used to respond to queries sourcing from these DMZ Windows DNS servers.
Does the GTM have a default configuration to respond with whatever pool member it has available regardless of the above Topology Records?
