How to setup F5 Big-IP LTM for Weblogic on different ports, same IP

There are two concepts:

• a node which is an IP address, typically a physical or virtual server instance

   

• a member which is a combination of IP address and port (port can also be any (0 or wildcard meaning all ports)), typically an application instance behind the IP address:port listener in a server

   

A load balancing pool has members, not nodes. You can have three members in a pool, all having same IP address but each a different port.

Thus you scenario of three physical nodes (=3 IP addresses), each having 3 WebLogic instances listening on different ports is feasible. You can have all those 9 members in the same load balancing pool.
