Abstract:
In one embodiment, a method generally includes a first edge (E) node in a network receiving an encapsulated data packet, wherein the encapsulated data packet comprises an outer header and a data packet, wherein the outer header comprises a first router locator (RLOC) corresponding to the first E node, wherein the data packet comprises an internet protocol (IP) header, and wherein the IP header comprises a destination endpoint identification (EID) corresponding to a host H. The first E node determines whether the host H is attached to the first E node. And in response to the first E node determining the host is attached to the first E node, the first E node forwards the data packet to the host H. The first E node receives a message from another node after the host H detaches from the first E node and reattaches to another E node, wherein the message comprises the destination EID.
