2. Fetch intop1-l2tp04 file
3. Launch ContainerLab intop1-l2tp04.yml topology:

   containerlab deploy --topo intop1-l2tp04.yml  

4. Destroy ContainerLab intop1-l2tp04.yml topology:

   containerlab destroy --topo intop1-l2tp04.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-l2tp04.tst file here
3. Launch intop1-l2tp04.tst test:
