  1. Install ContainerLab as described here
  2. Fetch rout-static14 file
  3. Launch ContainerLab rout-static14.yml topology: 

   containerlab deploy --topo rout-static14.yml
4. Destroy ContainerLab rout-static14.yml topology: 

   containerlab destroy --topo rout-static14.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 rout-static14.tst file here
  3. Launch rout-static14.tst test: 

   java -jar ../../rtr.jar test tester rout-static14 path ./ temp ./ wait
4. Destroy freeRtr rout-static14.tst test: 

   Ctrl-C (In freeRtr test window)
