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.)

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

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.
