It depends on the implementation of the control plane and how you maintain the mesh between the different servers (L2<=>L3 for arp resolution, mac learning). Historically vxlan was a multicast thing, but not anymore. Flannel (popular among the container networking solutions) will maintain its state in etcd by watching the Kubernetes resources then program the linux data plane with static unicast entries for the neighbors. |
