SD-WAN Zone (virtual-wan-link) with Disabled Status

Hi,

I am trying to configure SD-WAN but not sure why I am getting a disabled status on the SD-WAN zones as below:

Interface: virtual-wan-link

Link: *greyed arrow pointing down* (disabled)

Type: SD-WAN Zone

Interface: Test

Link: *greyed arrow pointing down* (disabled)

Type: SD-WAN Zone

Members:

wanport_1 (green icon)

wanport_2 (red icon)

Any reason why this is happening? How do I enable the sdwan zone?

Thanks!
