ContainerLabfreeRtr CLI

1. Install ContainerLab as described here
2. Fetch intop8-eth01 file
3. Launch ContainerLab intop8-eth01.yml topology:

   containerlab deploy --topo intop8-eth01.yml  

4. Destroy ContainerLab intop8-eth01.yml topology:

   containerlab destroy --topo intop8-eth01.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 intop8-eth01.tst file here
3. Launch intop8-eth01.tst test:
