Trying to create a virtual interface so that I can assign a second IP to eth0 on a Pi B+ running Raspbian Stretch. I've seen references to setting it up in dhcpcd.conf and interfaces, but nothing I've tried seems to be working. Basically, I need:
eth0 = 10.0.0.2/24 with a gateway of 10.0.0.1 and
eth0:1 = 172.16.0.20/24 with no default gateway
Can anyone help me with config files or documentation? I've spent the day searching and reading.
