An\nexternal load balancer is not needed.\n\nThere are two types of bundled load balancing:\n\n- **Layer 2** : All load balancer nodes and VIPs must be in the same Layer 2\n subnet. The gateway of the load balancer subnet must listen to gratuitous ARP\n messages and forward ARP packets to the load balancer nodes. See\n [Bundled load balancing with MetalLB](/kubernetes-engine/distributed-cloud/bare-metal/docs/installing/bundled-lb).\n\n- **BGP** : This load-balancing mode supports the advertisement of ServiceType\n LoadBalancer virtual IP addresses (VIPs) through external Border\n Gateway Protocol (eBGP) for your clusters. Your cluster network is an autonomous\n system, which interconnects with another autonomous system, an external network,\n through peering. See\n [Bundled load balancing with BGP](/kubernetes-engine/distributed-cloud/bare-metal/docs/how-to/lb-bundled-bgp).\n\nThe following diagram shows an example network topology where bundled MetalLB\nload balancers are located on the control plane nodes.\n\nManual load balancer mode\n\nIf you choose manual load balancing, Google Distributed Cloud does not deploy load\nbalancers. This allows more flexibility than bundled load balancing and there\nare no L2 network requirements.\n\nYou must configure your control plane nodes' VIPs on an external load\nbalancer before installing the cluster. After installation, you must pick a load\nbalancing solution for Kubernetes Services and Ingresses.\n\nThe following diagram shows an example network topology of a cluster using\nmanual load balancing mode with an external load balancer."]]
