  1. Install ContainerLab as described here
  2. Fetch mpls-te12 file
  3. Launch ContainerLab mpls-te12.yml topology:

   containerlab deploy --topo mpls-te12.yml  
4. Destroy ContainerLab mpls-te12.yml topology:

   containerlab destroy --topo mpls-te12.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-te12.tst file here
  3. Launch mpls-te12.tst test:

   java -jar ../../rtr.jar test tester mpls-te12 path ./ temp ./ wait
4. Destroy freeRtr mpls-te12.tst test:

   Ctrl-C (In freeRtr test window)
