 To make sure that ONOS is aware of the compute nodes, the following commands will send a ping over the fabric interface on the head node and each compute node.
 
 ```
-ping -c 1 -I fabric 8.8.8.8
+ping -c 1 10.6.1.254
 for h in $(cord prov list | grep "^node" | awk '{print $2}'); do
-ssh -i ~/.ssh/cord_rsa -qftn ubuntu@$h ping -c 1 -I fabric 8.8.8.8;
+ssh -i ~/.ssh/cord_rsa -qftn ubuntu@$h ping -c 1 10.6.1.254;
