A Virtual Router (VR) is described that can move freely from one physical router to another in a network. Embodiments enable a network operator to configure a network management primitive that supports live migration of VRs from one physical router to another. To minimize disruptions, VRs allow a migrated control plane from a source router to clone its data plane state from the source router at a destination router while continuing to update its data plane state at the source router. Embodiments temporarily forward packets using both router location data planes to support asynchronous migration of links.
