Hi Neil,

 

You can achieve an active/standby set up by using Global Availability as the load balancing method:

 

BIG-IP GTM distributes DNS name resolution requests to the first available virtual server in a pool. BIG-IP GTM starts at the top of a manually configured list of virtual servers and sends requests to the first available virtual server in the list. Only when the virtual server becomes unavailable does BIG-IP GTM send requests to the next virtual server in the list. Over time, the first virtual server in the list receives the most requests and the last virtual server in the list receives the least requests.
