Hi,

 

In GTM (BigIP DNS in version 12.0) :

 

  • a server is a physical object
  • a virtual server is the IP address / port combinaison of the load balanced service

a server can be :

 

  • a load balancer defined with management IP (F5 LTM, Radware, Cisco).
  • the server hosting multiple virtual hosts with several IPs

a virtual server can be a load balancer virtual server or a single service on a dedicated server.

 

if you want to load balance only a service on a server with the same IP, you need to create both server and virtual server with same IP.
