Quickly tested with our old friend olsrd, works fine:

Having a look at Mathieu's zip now...

"In July 2005, after several failed attempts to legalise software
patents in Europe, the patent establishment changed its strategy.
Instead of explicitly seeking to sanction the patentability of
software, they are now seeking to create a central European patent
court, which would establish and enforce patentability rules in their
favor, without any possibility of correction by competing courts or
democratically elected legislators."

You may also be interested in a quick integration test I built using
network-lab [0]

It's not a great set of unit tests like you would hope to find in a
modern language, but it does go a long way to allowing quick testing of
changes and only takes a few seconds to run.

My colleagues are divided on that subject.  Matthieu is rather fond of
Docker, while Gwendoline prefers nemu.

Hi, myself and Justin Kilpatrick have done a lot of this kind of stuff, and
Docker is kind of a distraction IMO. You're better off using raw network
namespaces. Here's a script we made to generate virtual networks with
configurable packet loss and latency from a json config format:

https://github.com/sudomesh/network-lab

You can try using this, or just read through it to learn how to make your
own.

Is the filesystem shared between the containers?  If it is, careful with
not sharing state files (check the -S option in the manual page).

What's the tunnelling technology?  Does it carry IPv6?  Is there
a link-local address on the interfaces?

What does tcpdump say?
