Why does the physical port which has multi sub-interfaces belong to VPN0 for SD-WAN service VPN?

Hi 

I am wondering the reason why the physical port which has multi sub-interfaces belongs to VPN0, but the sub-interfaces belong to VPN1?

Hi,

Don't overthink it :-) This has to do with some internals of implementation. If you need to apply interface level configs, do them on the parent interface in VPN0, everything else goes onto the sub-interfaces in the service VPN(s).
