+# CiliumL2AnnouncementPolicy — ARPs each LoadBalancer IP (from lb-ippool) on the
+# LAN so the EXTERNAL-IP is actually reachable. Without it, LB-IPAM assigns IPs
+# but nothing answers ARP (100% packet loss / incomplete ARP). One node per IP
+# holds the lease (leaderElection) to avoid ARP flapping. Requires kube-proxy
+# replacement (enabled) and Cilium L2 announcements (default since v1.14).
