In this demonstration, we are going to create a VNet-to-VNet connection using PowerShell. 

In the following steps, we will create two VNets together with the gateway configurations and subnets. We then create a VPN connection between the two VNets. We are going to set up a connection in the same Azure subscription. In the first step, we are going to plan the IP address ranges for the network configurations. We need to make sure that none of the VNet or local ranges overlap.
