  1. Install ContainerLab as described here
  2. Fetch conn-lisp04 file
  3. Launch ContainerLab conn-lisp04.yml topology: 

   containerlab deploy --topo conn-lisp04.yml
4. Destroy ContainerLab conn-lisp04.yml topology: 

   containerlab destroy --topo conn-lisp04.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 conn-lisp04.tst file here
  3. Launch conn-lisp04.tst test:
