This repository contains everything to create a custom Debian minimal ISO for an unattended installation so that the
resulting machine joins automatically an underlay via unnumbered BGP. Check profiles/custom.postinst for networking details.
Build the image localhost/machine and wait several minutes:
$ docker build -t localhost/machine .Start the test lab with:
$ sudo containerlab deploy
