If you have only VLAN-backed logical switches, you can connect the switches to VLAN ports on a tier-0 or tier-1 router so that NSX-T Data Center can provide layer-3 services.


Verify that Manager mode is selected in the NSX Manager user interface. See NSX Manager. If you do not see the Policy and Manager mode buttons, see Configure the User Interface Settings.


  1. With admin privileges, log in to NSX Manager.
  2. Locate the router in Networking > Tier-0 Logical Routers or Networking > Tier-1 Logical Routers and select it.
  3. Click the Configuration tab and select Router Ports.
  4. Click Add.
  5. Enter a name for the router port and optionally a description.
  6. In the Type field, select Centralized.
  7. For URPF Mode, select Strict or None.
    URPF (unicast Reverse Path Forwarding) is a security feature.
  8. (Required) Select a logical switch.
  9. Select whether this attachment creates a switch port or updates an existing switch port.
    If the attachment is for an existing switch port, select the port from the drop-down menu.
  10. Enter the router port IP address in CIDR notation.
  11. Click Add.
