No ARP reply in case of HAproxy vIP and EgressIP assigned to the same INFRA node

Solution In Progress - Updated -


  • In a scenario where the HAproxy Ingress vIP (floating IP address associated to the OpenShift Application Domain) is assigned to the same INFRA node where also the EgressIPof the openshift-gitops (ArgoCD) is allocated, any ARP request for the EgressIP address (ARP request sent from the node that is hosting the HAproxy Ingress vIP) won't be answered at all.
  • As result of the behaviour above described, the authentication in openshift-gitops (ArgoCD integrated with OpenShift) will systematically fail because from the INFRA node isn't possible to resolve the EgressIP.


  • Red Hat OpenShift 4 with the OVN-Kubernetes Container Network Interface (CNI) plugin.
  • openshift-gitops operator 1.7.1
