Exercise 4.1: Incomplete question and unclear answers

Hello all,

In exercise 4.1 at network plugins, a list with six plugins is given.

  • The second bullet (Calico with Canal) contains a link to a deprecated site and I don't know how to get to the correct Canal site.
  • The third bullet is empty. When looking at the answers, it seems that it should describe Weave Net.

At the answers, multiple plugins are claimed to be layer 2 plugins. I have looked at each plugin but I cannot find any proof of this. Where can I find the specific information? Note: since I only had a correct link to Flannel, that is the only site where I could look for it but I didn't find it.
