  11 Testcase for router/FloatingIP & net assoc mutual exclusivity
  12
  13 A testcase for ODL Bug 6962, testing whether a subnet with a router can be
  14 network associated:
  15 - Create two VMs, each in a subnet with a router
  16 - Network assoc the two networks in a VPN iRT=eRT
  17 - Try to ping from one VM to the other
  18 - Assign a floating IP to a VM
  19 - Ping it
