      Description of problem:

      During cluster installation if the host systems had multiple dual-stack interfaces configured via install-config.yaml, the installation will fail. Notably, when a single-stack ipv4 installation is attempted with multiple interfaces it is successful. Additionally, when a dual-stack installation is attempted with only a single interface it is successful.

      Version-Release number of selected component (if applicable):

      Reproduced on 4.12.1 and 4.12.7

      How reproducible:

      100%

      Steps to Reproduce:

      1. Assign an IPv4 and an IPv6 address to both the apiVIPs and ingressVIPs parameters in the install-config.yaml
      2. Configure all hosts with at least two interfaces in the install-config.yaml
      3. Assign an IPv4 and an IPv6 address to each interface in the install-config.yaml
      4. Begin cluster installation and wait for failure

      Actual results:

      Failed cluster installation

      Expected results:

      Successful cluster installation
