For business continuity purposes, Virtual Machine (VM) migration across data centers is commonly used in situations such as data- center maintenance, migration, consolidation, expansion, or disaster avoidance. The IETF community has recognized that IP renumbering of servers (i.e., VMs) after the migration is usually complex and costly. To allow the migration of a VM from one data center to another without IP renumbering, the subnet on which the VM resides needs to be extended across these data centers.
