  1. Install ContainerLab as described here
  2. Fetch rout-mcast03 file
  3. Launch ContainerLab rout-mcast03.yml topology: 

   containerlab deploy --topo rout-mcast03.yml
4. Destroy ContainerLab rout-mcast03.yml topology: 

   containerlab destroy --topo rout-mcast03.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 rout-mcast03.tst file here
  3. Launch rout-mcast03.tst test: 

   java -jar ../../rtr.jar test tester rout-mcast03 path ./ temp ./ wait
4. Destroy freeRtr rout-mcast03.tst test: 

   Ctrl-C (In freeRtr test window)
