  11 Test whether router assoc can coexist with floating IP
  12 - Create VM1 in net1 with a subnet which is connected to a router
  13     which is connected with the gateway
  14 - Create VM2 in net2 with a subnet without a router attached.
  15 - Create bgpvpn with iRT=eRT
  16 - Assoc the router of net1 with bgpvpn and assoc net 2 with the bgpvpn
  17 - Try to ping from one VM to the other
  18 - Assign a floating IP to the VM in the router assoc network
  19 - Ping it the floating ip
