When do you need to put a gateway for SDWAN interfaces? The default when adding a new interface member to the SD-WAN group is 0.0.0.0. If you have the default route set already in your routing table, do you still need to specify the gateway in SD-WAN interface?

    Hello,

     

    If an interface has static IP configuration then you need to provide the gateway member while adding that interface to SD-WAN zone. In case of DHCP IP configuration, DHCP server provides the gateway information so you can put 0.0.0.0 while adding the interface into SD-WAN zone.
