  1. Install ContainerLab as described here
  2. Fetch intop9-bgp08 file
  3. Launch ContainerLab intop9-bgp08.yml topology: 

   containerlab deploy --topo intop9-bgp08.yml
4. Destroy ContainerLab intop9-bgp08.yml topology: 

   containerlab destroy --topo intop9-bgp08.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 intop9-bgp08.tst file here
  3. Launch intop9-bgp08.tst test: 

   java -jar ../../rtr.jar test tester intop9-bgp08 path ./ temp ./ wait
4. Destroy freeRtr intop9-bgp08.tst test: 

   Ctrl-C (In freeRtr test window)
