--- # CiliumL2AnnouncementPolicy — ARP-announce LoadBalancer VIPs on the node LAN so hosts on # 192.168.1.0/24 can reach Gateway listeners at the pool IP (l2announcements.enabled=true in the # Cilium HelmRelease turns on the controller; this policy scopes WHAT/WHERE it announces). # Announces on the primary ethernet interface. On Proxmox VMs the NIC is typically ens18/eth0; # `^e(n|th)` matches ens*/enp*/eth* so the exact name need not be pinned. VERIFY-AT-BRINGUP: if # announcement fails, confirm the node's primary NIC name (`ip -o link`) matches this selector. apiVersion: cilium.io/v2alpha1 kind: CiliumL2AnnouncementPolicy metadata: name: default-l2 spec: loadBalancerIPs: true # announce LoadBalancer Service VIPs (Gateway listeners) externalIPs: false interfaces: - ^e(n|th) nodeSelector: matchLabels: kubernetes.io/os: linux
