Obtaining vWAN details
Obtain the following details about the vWAN service:

The Remote_sites.txt file serves as the input for Azure functions. The file contains information about all sites that want to connect to vWAN. You will store the file in a storage blob. You must include the following information in the file:
- Site name (Azure uses this as an identifier)
- FortiGate public IP address
- Internal networks behind the FortiGate that need access to the vWAN
- BGP ASN and peering IP address to use
- Login credentials
