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

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

   containerlab destroy --topo crypt-ssh.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-ssh.tst file here
  3. Launch crypt-ssh.tst test: 

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

   Ctrl-C (In freeRtr test window)
