  1. Install ContainerLab as described here
  2. Fetch conn-sreth03 file
  3. Launch ContainerLab conn-sreth03.yml topology:

   containerlab deploy --topo conn-sreth03.yml  
4. Destroy ContainerLab conn-sreth03.yml topology:

   containerlab destroy --topo conn-sreth03.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-sreth03.tst file here
  3. Launch conn-sreth03.tst test:

   java -jar ../../rtr.jar test tester conn-sreth03 path ./ temp ./ wait
4. Destroy freeRtr conn-sreth03.tst test:

   Ctrl-C (In freeRtr test window)
