Using the default sdwan virtual wanlink instead of creating a new generic virtual wanlink

Hello Expert,

I configured sdwan on my fortigate  80F, but I use the virtual wanlink and created the two wan interface under (virtual wanlink)  instead of creating a new vpn as showing in the demo.

Will the use of the default virtual wanlink cause any issues.

Or should not use the default virtual wanlink.

Regards
