GTM Three Load Balancing Method
Hello,
Currently, the following Three-Tier LB has been setup:
Preferred: Global Availability
Alternate: None
Fallback: Drop Packet
And two pools ae configured in the Member Order:
0 - Pool A
1 - Pool B
Referring to the following document, is the sentence marked in bold desribing the behavior of GTM.
And if so, when Fallback is set to "Drop Packet" does this mean that the next server would be selected. For example, if Pool A becomes unavailable, GTM would not select one from Pool B.
Please advise.
Thanks
About the Global Availability load balancing method
The Global Availability load balancing method distributes DNS name resolution requests based on the order of resources in a list. Using global availability, BIG-IP® DNS sends a request to the first available resource in a list. Only when a resource becomes unavailable does BIG-IP DNS send requests to the next resource in the list. You can only select the next resource in the list if the Fallback load balancing method is set to None. Over time, the first resource in the list receives the most requests and the last resource in the list receives the least requests.
