During Oracle RAC failover, the surviving RAC node issues GARP twice in RHEL 6

- During Oracle RAC failover, the surviving RAC node issues Gratuitous ARP (GARP) twice. The first one has the correct MAC address and this is immediately followed by a second GARP but with an incorrect MAC address (it’s using the MAC address of the default gateway).
Environment
