Install NSX Edge on ESXi using the NSX UI, the vSphere web client, or the command-line OVF tool. What to read next NSX Edge Installation RequirementsThe NSX Edge provides routing services and connectivity to networks that are external to the NSX deployment. NSX Edge nodes provide a pool of capacity for running centralized services and is required if you want to deploy a tier-0 router or a tier-1 router with stateful services such as network address translation (NAT), VPN, and so on. NSX Edge Networking SetupNSX Edge can be installed using ISO, OVA/OVF, or PXE start. Regardless of the installation method, make sure that the host networking is prepared before you install NSX Edge. NSX Edge Installation MethodsInstall NSX Edge on an ESXi host using NSX Manager UI (recommended method), vSphere Web Client (from UI or vSphere command-line OVF tool) or as physical severs. Create an NSX Edge Transport NodeNSX Edge nodes are service appliances with pools of capacity, dedicated to running network and security services. Configure NSX Edge DPDK InterfacesConfigure an NSX Edge VM with an N-VDS switch to carry both overlay and external traffic. Manually Deploying NSX Edge Node Outside of NSXIn addition to deploying and configuring NSX Edge from the NSX Manager, you can manually deploy NSX Edge either as a VM in VMware vCenter or a Bare Metal server. Create an NSX Edge ClusterHaving a multi-node cluster of NSX Edges helps ensure that at least one NSX Edge is always available. Remove NSX Edge Nodes from an Edge ClusterRemove NSX Edge nodes with Tier-1 Gateways or Tier-0 Gateway configured with service router (SR), DHCP and metadata proxy. Relocate and Remove an NSX Edge Node from an NSX Edge ClusterStarting with NSX 4.0.1.1, you can use the NSX relocate and remove API to relocate the service configurations of an NSX Edge node to another standby NSX Edge node in the same NSX Edge cluster and then remove the Edge node from the Edge cluster.
