Resolve 2 IPs at the same time, with failover in a 3rd one

Hello,

My understand, in your scenario you can run with a single pool and a fallback IP:

To get multiple answers, change the "Maximum Answers Returned" on pool properties.

E.g.

WideIP: www.my.domain

Pools:  Pool_A

Last Resort Pool: None

Pool_A:

  Properties:

    Maximum Answers Returned: 2

  Members:

    1.1.1.1

    2.2.2.2

    Load Balancing Method:

      Preferred: RR

      Alternate: RR

      Fallback: Fallback IP

    Fallback IP: 3.3.3.3

If you need to work with a last resort pool setup, you can:

WideIP: www.my.domain

Pools:  Pool_A

Last Resort Pool: Pool_B

Pool_A:

  Maximum Answers Returned: 2

  Members:

    1.1.1.1

    2.2.2.2

  Load Balancing Method:

    Preferred: RR

    Alternate: RR

    Fallback: None

  Fallback IP: 0.0.0.0

Pool_B:

  Members:

    3.3.3.3

.........

I hope this helps.

Best Regards
