==Modern Day Uses== Although the original uses for RARP have been superseded by different protocols, some modern-day protocols use RARP to handle MAC migration, particularly in virtual machines, using a technique originating in [[QEMU]]. Examples include: * Cisco's [[Overlay Transport Virtualization]] (OTV). RARP is used to update the layer 2 forwarding tables when a MAC address moves between data centers. * [[VMware vSphere]]'s vMotion.<ref>{{Cite web |last=Deshpande |first=Venky |date=22 July 2013 |title=VXLAN Series β How vMotion impacts the forwarding table β Part 6 |url=http://www.soviet-empire.com/ussr/viewtopic.php?t=50411 |access-date=15 March 2023 |website=vmware}}</ref> RARP is used when a VM MAC moves between hosts.
