here is the ipv6 tops:
  1. Install ContainerLab as described here
  2. Fetch crypt-insp02 file
  3. Launch ContainerLab crypt-insp02.yml topology:

   containerlab deploy --topo crypt-insp02.yml  
4. Destroy ContainerLab crypt-insp02.yml topology:

   containerlab destroy --topo crypt-insp02.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-insp02.tst file here
  3. Launch crypt-insp02.tst test:

   java -jar ../../rtr.jar test tester crypt-insp02 path ./ temp ./ wait
4. Destroy freeRtr crypt-insp02.tst test:

   Ctrl-C (In freeRtr test window)
