  1. Install ContainerLab as described here
  2. Fetch intop1-bgp22 file
  3. Launch ContainerLab intop1-bgp22.yml topology: 

   containerlab deploy --topo intop1-bgp22.yml
4. Destroy ContainerLab intop1-bgp22.yml topology: 

   containerlab destroy --topo intop1-bgp22.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-bgp22.tst file here
  3. Launch intop1-bgp22.tst test: 

   java -jar ../../rtr.jar test tester intop1-bgp22 path ./ temp ./ wait
4. Destroy freeRtr intop1-bgp22.tst test: 

   Ctrl-C (In freeRtr test window)
