Configure a Physical Ethernet Interface for SD-WAN

Configure Ethernet Layer 3 interfaces with SD-WAN functionality.
In Panorama™, configure a physical, Layer 3 Ethernet interface and enable SD-WAN functionality. To configure a physical interface, you must assign it an IPv4 address and a fully qualified Next Hop Gateway, and assign an SD-WAN Interface Profile to the interface. (SD-WAN supports only a Layer 3 interface type; it does not support Layer 2 networks such as VPLS.)
After you use Panorama to create a VPN cluster and export your hub and branch information in the CSV, Auto VPN configuration in the SD-WAN plugin uses this information to generate a configuration for the associated branches and hubs that includes the predefined SD-WAN zones and creates secure VPN tunnels between SD-WAN branches and hubs. Auto VPN configuration also generates the BGP configuration if you enter BGP information the CSV or in Panorama when you add an SD-WAN branch or hub.
  1. Select
    , select the appropriate template from the
    context drop-down, select a slot number, such as Slot1, and select an interface (for example, ethernet1/1).
  2. Select the
    Interface Type
  3. Select a
    Virtual Router
    or create a new Virtual Router.
  4. Assign the
    Security Zone
    that is appropriate for the interface you’re configuring.
    For example, if you are creating an uplink to an ISP, you must know that the Ethernet interface you chose is going to an untrusted zone.
  5. On the
    Enable SD-WAN
  6. Select
    of address:
    • Static
      —In the
      an IPv4 address and prefix length for the interface. You can use a defined variable, such as $uplink, with a range of addresses. Enter the fully qualified IPv4 address of the
      Next Hop Gateway
      (the next hop from the IPv4 address you just entered). The Next Hop Gateway must be on the same subnet as the IPv4 address. The Next Hop Gateway is the IP address of the ISP’s default router that the ISP gave you when you bought the service. It is the next hop IP address to which the firewall sends traffic to reach the ISP’s network, and ultimately, the internet and the hub.
    • PPPoE
      PPPoE authentication for DSL links, enter the
      , and
      Confirm Password
    • DHCP Client
      —It is critical that DHCP assigns a default gateway, also known as the next hop gateway for the ISP connection. The ISP will provide all the necessary connectivity information, such as dynamic IP address, DNS servers, and the default gateway.
      If the interface is on a hub, choose the Static address type; DHCP Client is not supported on a hub, but is supported on branches.
      If you select DHCP Client, be sure to disable the option
      Automatically create default route pointing to default gateway provided by server
      , which is enabled by default.
  7. On the
    tab, select an
    SD-WAN Interface Profile
    that you already created (or create a new SD-WAN Interface Profile) to apply to this interface. The SD-WAN Interface Profile has an associated link tag, so the interfaces where this profile is applied will have the associated link tag. An interface can have only one link tag.
  8. Click
    to save the Ethernet interface.
  9. Commit
    Commit and Push
    your configuration changes.
  10. (
    SD-WAN manual configuration only
    ) Configure a Virtual SD-WAN Interface. Auto VPN configuration will perform this task if you are using Auto VPN.
