In the Azure Networking 101 course/video, the instructor said doing Azure Transit via ExpressRoute Edge Routers can avoid VNet Peering data charge. I don't quite get it as there is data charge still on those two VNet Peering between Spoke VNets and Hub VNet that ExpressRoute terminates, isn't there?
Or he actually meant avoiding the data charge of VNet Peering between Spoke VNets? But what is the actual difference from commercial prospective? Traversing two VNet Peering through Hub VNet V.S. traversing one direct VNet Peering between two Spoke VNets.
