Fixed In:
2.1.0
Opened: Jul 23, 2025 Severity: 2-Critical
When the F5Ingress Controller is reinstalled, the internal interface annotations needed for Multiple External Gateway (MEG) are not added to the Traffic Management Microkernel (TMM). This prevents the creation of Open Virtual Network (OVN) routes in the cluster, causing egress traffic to drop from application pods via TMM.
Missing internal interface annotations prevent OVN routes from being added in the OpenShift (OCP) cluster, which causes egress traffic to drop from application pods through TMM.
1. MEG is enabled. 2. ICNI 2.0 is disabled. 3. F5 CNE Controller is reinstalled.
To mitigate the issue, use one of the following methods after reinstalling the F5Ingress Controller: 1. Delete the failed admin policies and reapply them. 2. Disable MEG and enable ICNI2.0. This actions will add the OVN routes and restore egress traffic for the application pods.
