Editing Reverse Address Resolution Protocol (section)

==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Although the original uses for RARP have been superseded by different protocols, some modern-day protocols use RARP to handle MAC migration, particularly in virtual machines, using a technique originating in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 – How vMotion impacts the forwarding table – 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.
