Hello everyone, as you may or may not have notices, there have been some changes to the way we handle topotests. There have been two major changes: a) topotests have been integrated into the frr repository b) topotests have gained docker support This mail is intended to give a brief overview of what this entails. # Topotests in FRR The topotests have moved from their own repository to tests/topotests in the main FRR repository. All the history has been imported and they can be used from this location just as before. However, this change enables us to send new topotests along with new features. Also it removes the hassle of checking which FRRouting version is running from the topotests. # Topotests docker support Raphael and me have come up with a Dockerfile and accompanying shell scripts which can be used to build a docker image which provides an environment suitable to run the topotests in. This is purely an addition to the existing topotests. They can still be run as before. However, they can also be run by executing `make topotests` on any docker enabled system. (For now it's Linux only, but theoretical OS X should be possible) This relieves you from having to figure out how to install an Ubuntu with mininet, exabgp, libyang, etc. etc, as this part is done by the Dockerfile. More details about this can be found here: https://github.com/FRRouting/frr/tree/master/tests/topotests/docker This feature is relatively new, so there might still be a few dragons, but generally, it should be ready for a test drive, if you feel so inclined. Feel free to provide bug reports and suggestions for improvement, or better yet: pull requests. :) All Best, Chris
