ContainerLabfreeRtr CLI

1. Install ContainerLab as described here
2. Fetch mpls-pwe18 file
3. Launch ContainerLab mpls-pwe18.yml topology:

   containerlab deploy --topo mpls-pwe18.yml  

4. Destroy ContainerLab mpls-pwe18.yml topology:

   containerlab destroy --topo mpls-pwe18.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-pwe18.tst file here
3. Launch mpls-pwe18.tst test:

   java -jar ../../rtr.jar test tester mpls-pwe18 path ./ temp ./ wait

4. Destroy freeRtr mpls-pwe18.tst test:

   Ctrl-C (In freeRtr test window)
