  1. Install ContainerLab as described here
  2. Fetch rout-isis041 file
  3. Launch ContainerLab rout-isis041.yml topology: 

   containerlab deploy --topo rout-isis041.yml
4. Destroy ContainerLab rout-isis041.yml topology: 

   containerlab destroy --topo rout-isis041.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-isis041.tst file here
  3. Launch rout-isis041.tst test:
