Install NSX Edge on ESXi using the NSX-T UI, the vSphere web client, or the command-line OVF tool. NSX Edge Installation RequirementsThe NSX Edge provides routing services and connectivity to network NSX Edges that are external to the NSX-T Data Center deployment. An NSX Edge 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 Setup NSX 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, or the vSphere command-line OVF tool. Create an NSX Edge Transport NodeYou can add an NSX Edge VM to the NSX-T Data Center fabric and proceed to configure it as a NSX Edge transport node VM. Create an NSX Edge ClusterHaving a multi-node cluster of NSX Edges helps ensure that at least one NSX Edge is always available. Install an NSX Edge on ESXi Using the vSphere GUIYou can use the vSphere Web Client or vSphere Client to interactively install an NSX Edge on ESXi. Install NSX Edge on Bare MetalUse PXE server to automate installation of NSX Edge on a bare metal server or use ISO file to install NSX Edge as a VM appliance or on a bare metal server. Join NSX Edge with the Management PlaneJoining NSX Edges with the management plane ensures that the NSX Manager and NSX Edges can communicate with each other. Configure an NSX Edge as a Transport NodeAfter manually installing NSX Edge on ESXi or Bare Metal, configure an NSX Edge to the NSX-T Data Center fabric as a transport node.
