  1. Install ContainerLab as described here
  2. Fetch crypt-ike112 file
  3. Launch ContainerLab crypt-ike112.yml topology: 

   containerlab deploy --topo crypt-ike112.yml
4. Destroy ContainerLab crypt-ike112.yml topology: 

   containerlab destroy --topo crypt-ike112.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-ike112.tst file here
  3. Launch crypt-ike112.tst test:
