here is the interface:
  1. Install ContainerLab as described here
  2. Fetch mpls-pwhe01 file
  3. Launch ContainerLab mpls-pwhe01.yml topology: 

   containerlab deploy --topo mpls-pwhe01.yml
4. Destroy ContainerLab mpls-pwhe01.yml topology: 

   containerlab destroy --topo mpls-pwhe01.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 mpls-pwhe01.tst file here
  3. Launch mpls-pwhe01.tst test: 

   java -jar ../../rtr.jar test tester mpls-pwhe01 path ./ temp ./ wait
4. Destroy freeRtr mpls-pwhe01.tst test: 

   Ctrl-C (In freeRtr test window)
