  1. Install ContainerLab as described here
  2. Fetch crypt-wireguard05 file
  3. Launch ContainerLab crypt-wireguard05.yml topology: 

   containerlab deploy --topo crypt-wireguard05.yml
4. Destroy ContainerLab crypt-wireguard05.yml topology: 

   containerlab destroy --topo crypt-wireguard05.yml
5. Copy-paste configuration for each node in the lab topology

  1. Fetch or compile freeRtr rtr.jar file.
    You can grab it here
  2. Fetch crypt-wireguard05.tst file here
  3. Launch crypt-wireguard05.tst test: 

   java -jar ../../rtr.jar test tester crypt-wireguard05 path ./ temp ./ wait
4. Destroy freeRtr crypt-wireguard05.tst test: 

   Ctrl-C (In freeRtr test window)
