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