Configure multiple domain on weblogic

Question

We need to configure a weblogic 12c version like the example below. However I can't find the configuration to add Admin_Server2 and Admin_Server3 to machines 2 and 3. See wrongly configured illustration.

Can you please help or provide pointers on how to configure Ideal Weblogic Configuration.

Ideal Weblogic Configuration

Machine1
Admin_Server1
Managed_Server1
Managed_Server2
Managed_Server3

Machine2
Admin_Server2
Managed_Server4
Managed_Server5
Managed_Server6

Machine3
Admin_Server3
Managed_Server7
Managed_Server8
Managed_Server9

Weblogic Wrongly Configured

Machine1
Admin_Server1
Managed_Server1
Managed_Server2
Managed_Server3

Machine2
Managed_Server4
Managed_Server5
Managed_Server6

Machine3
Managed_Server7
Managed_Server8
Managed_Server9

Configuration 2

I am not sure if this is the correct way of creating multiple domains in weblogic.

1) From  /Middleware/oracle_common/common/bin/ path execute config.sh to run the GUI installer and create two more Weblogic domains.
2) Create AdminServer-2, Managed Servers and Machine2
3) Assign different ports to AdminServer2, Managed Servers and Machine2 with IP address set to currently configured IP address for the machine or VM
4) Repeat steps 2 and 3 for AdminServer3, MS-3 and Machine3 but and use ports which are not used by Servers on Domains 1 and 2.
5) Result is below

http://<IP_ADDRESS>:7001/console
    Machine1
    Admin_Server1
    Managed_Server1
    Managed_Server2
    Managed_Server3

http://<IP_ADDRESS>:7006/console
    Machine2
    Admin_Server2
    Managed_Server4
    Managed_Server5
    Managed_Server6

http://<IP_ADDRESS>:7011/console
    Machine3
    Admin_Server3
    Managed_Server7
    Managed_Server8
    Managed_Server9

Note I need to login to each weblogic server in order to configure further details on each managed servers.

It is important to understand what a WebLogic Domain is.

A WebLogic domain could be seen as a group of resources which are grouped and configured together, in a domain. The domain configuration is managed through the admin server. So, each domain has one and only one admin server. And every admin server belongs to only one domain.

From what I have understood is that you want to create a separate domain per machine. So you have to install and configure a WebLogic domain separately on each and every machine. During installation you don't you should only configure one machine.
