+## setup and deploy
+
+Using flux for reconciliation.
+
+**Restart:**
+
+Occasionally, Cilium's eBPF maps for L2 announcements can get "stale" after a configuration change (like switching from Local to Cluster). Perform a rolling restart of the Cilium pods to clear the state:
+
+```bash
+```
+
+``` bash
+POD_NAME=$(kubectl get pod -l 'app.kubernetes.io/name'=cilium-agent -n cilium -o jsonpath='{.items[0].metadata.name}')
+kubectl exec -n cilium  ${POD_NAME} -c cilium-agent -- cilium-dbg status
+```
+
+**list load balancers ip pools:**
+*Required after changes*
+
+```bash
+kubectl get CiliumLoadBalancerIPPool -A 
+```
