    Hello Tim.

    ​

    You have many ways to configure this. One idea which comes to my mind right now is to have 3 pools.

    • Pool_A: 20 webservers
    • Pool_B: 20 webservers
    • Pool_C: 20 + 20 webservers

    ​

    You can use a table variable to define what pool to use in every moment. Initially this variable is set to Pool_C, and depending on the status of Pool_A and Pool_B you can switch the pool selection.

    ​This is one approach which can give some idea to develop your own scenario.

    Also, another idea is to use VIP-Tarjeting-VIP to set one VIP which has one pool with two nodes in RR (VIP_A and VIP_B). This is another approach which can help.

Thanks Dario. I was able to successfully implement the Active/Passive Scenario. It's working well.
