      This is a clone of issue OCPBUGS-3993. The following is the description of the original issue:

      Description of problem:
      On Openshift on Openstack CI, we are deploying an OCP cluster with an additional network on the workers in install-config.yaml for integration with Openstack Manila.

      compute:
      - name: worker
        platform:
          openstack:
            zones: []
            additionalNetworkIDs: ['0eeae16f-bbc7-4e49-90b2-d96419b7c30d']
        replicas: 3
      

      As a result, the egressIP annotation includes two interfaces definition:

      $ oc get node ostest-hp9ld-worker-0-gdp5k -o json | jq -r '.metadata.annotations["cloud.network.openshift.io/egress-ipconfig"]' | jq .                                 
      [
        {
          "interface": "207beb76-5476-4a05-b412-d0cc53ab00a7",
          "ifaddr": {
            "ipv4": "10.46.44.64/26"
          },
          "capacity": {
            "ip": 8
          }
        },
        {
          "interface": "2baf2232-87f7-4ad5-bd80-b6586de08435",
          "ifaddr": {
            "ipv4": "172.17.5.0/24"
          },
          "capacity": {
            "ip": 10
          }
        }
      ]
      

      According to huirwang, egressIP only works for primary interface on the node.

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

       4.12.0-0.nightly-2022-11-22-012345
      RHOS-16.1-RHEL-8-20220804.n.1
      

      How reproducible:

      Always
      

      Steps to Reproduce:

      Deploy cluster with additional Network on the workers
      

      Actual results:

      It is possible to select an egressIP network for a secondary interface
      

      Expected results:

      Only primary subnet can be chosen for egressIP
