  1. Install ContainerLab as described here
  2. Fetch rout-lsrp16 file
  3. Launch ContainerLab rout-lsrp16.yml topology: 

   containerlab deploy --topo rout-lsrp16.yml
4. Destroy ContainerLab rout-lsrp16.yml topology: 

   containerlab destroy --topo rout-lsrp16.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-lsrp16.tst file here
  3. Launch rout-lsrp16.tst test:
