  1. Install ContainerLab as described here
  2. Fetch crypt-acl77 file
  3. Launch ContainerLab crypt-acl77.yml topology: 

   containerlab deploy --topo crypt-acl77.yml
4. Destroy ContainerLab crypt-acl77.yml topology: 

   containerlab destroy --topo crypt-acl77.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-acl77.tst file here
  3. Launch crypt-acl77.tst test: 

   java -jar ../../rtr.jar test tester crypt-acl77 path ./ temp ./ wait
4. Destroy freeRtr crypt-acl77.tst test: 

   Ctrl-C (In freeRtr test window)
