ContainerLabfreeRtr CLI

1. Install ContainerLab as described here
2. Fetch conn-vxlan03 file
3. Launch ContainerLab conn-vxlan03.yml topology:

   containerlab deploy --topo conn-vxlan03.yml  

4. Destroy ContainerLab conn-vxlan03.yml topology:

   containerlab destroy --topo conn-vxlan03.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-vxlan03.tst file here
3. Launch conn-vxlan03.tst test:

   java -jar ../../rtr.jar test tester conn-vxlan03 path ./ temp ./ wait

4. Destroy freeRtr conn-vxlan03.tst test:

   Ctrl-C (In freeRtr test window)
