  1. Install ContainerLab as described here
  2. Fetch rout-babel19 file
  3. Launch ContainerLab rout-babel19.yml topology: 

   containerlab deploy --topo rout-babel19.yml
4. Destroy ContainerLab rout-babel19.yml topology: 

   containerlab destroy --topo rout-babel19.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-babel19.tst file here
  3. Launch rout-babel19.tst test:
