Please advise how to properly create a virtual interface. Should I use the /etc/network/interfaces file or create a file in the /etc/network/interfaces.d directory? Are there any requirements for the name of the virtual interface?
I can't advise directly, but I will observe that a full and accurate response is likely to need knowledge of what Operating System (by named version) is running on your RPi board. 'RasPiOS' - as given in the title of the sub-forum in which this query is posted - is too vague to be helpful.

Networking
During Bullseye, we rolled out the use of the NetworkManager network controller as an option which could be selected in raspi-config. This is now the standard control mechanism for networking in most Linux distributions, and is now the default network controller for Bookworm, replacing the previous system, dhcpcd. NetworkManager does everything dhcpcd did, but adds a bunch of extra functionality, including the ability to connect to hidden wireless networks, to connect to virtual private networks (VPNs), and to use a Raspberry Pi as a wireless hotspot. It also includes a lot more customisation options for those who wish to fiddle with the nitty-gritty of their network connection.
