The most specific VS will be the one that matches the traffic irrespective of the order of creation or listing in the bigip.conf. Here is the order of precedence:

 

 

Host:port specific VS: 1.1.1.1:80

 

Host specific VS: 1.1.1.1:0

 

Port specific network VS: 1.1.1.0/24:80

 

Network VS: 1.1.1.0/24:0

 

Port specific wildcard VS: 0.0.0.0:80

 

Wildcard VS: 0.0.0.0:0
