Description

In larger environments the switch of the floating IP to a different host has to be announced via a unsolicited ARP packet to ensure that the switch updates it's ARP table accordingly. Without that a leader change is not propagated to the switch and on leader change access from other networks ends up at the wrong router port.

The change needed is minimal as just the parameter of the arping command has to be switched from -A to -U (https://github.com/OpenNebula/one/pull/425)
