  1. Install ContainerLab as described here
  2. Fetch conn-bridge19 file
  3. Launch ContainerLab conn-bridge19.yml topology: 

   containerlab deploy --topo conn-bridge19.yml
4. Destroy ContainerLab conn-bridge19.yml topology: 

   containerlab destroy --topo conn-bridge19.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-bridge19.tst file here
  3. Launch conn-bridge19.tst test: 

   java -jar ../../rtr.jar test tester conn-bridge19 path ./ temp ./ wait
4. Destroy freeRtr conn-bridge19.tst test: 

   Ctrl-C (In freeRtr test window)
