Abstract
A method for assisting communication of a source host upon movement from a first Data center (DC) to a second DC is disclosed. The method includes identifying that the source host has moved from the first DC to the second DC, ensuring that packets identifying a source as the source host in the second DC are copied to a control plane network element, and, for a first destination host identified in a first packet copied to the control plane network element and identified as a host that is not in the second DC, updating an Address Resolution Protocol (ARP)/Neighbor Discovery Protocol (NDP) cache of the source host by sending, to the source host, a first ARP message/unsolicited neighbor advertisement specifying a Media Access Control (MAC) address of an edge router associated with the source host in the second DC as a destination MAC address for the first destination host.
