  1. Install ContainerLab as described here
  2. Fetch intop1-isis04 file
  3. Launch ContainerLab intop1-isis04.yml topology: 

   containerlab deploy --topo intop1-isis04.yml
4. Destroy ContainerLab intop1-isis04.yml topology: 

   containerlab destroy --topo intop1-isis04.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 intop1-isis04.tst file here
  3. Launch intop1-isis04.tst test:
