Abstract

According to one example embodiment, an EID-NOTIFY packet is defined for use with the Location/Identifier Separation Protocol (LISP). A first-hop network element may send EID-NOTIFY responsive to decoding a data packet from a previously undetected host on its subnetwork. A site network element may receive EID-NOTIFY, and send a MAP-REGISTER message to a mapping system. EID-NOTIFY may have substantially the same format as MAP-NOTIFY. This may enable the site network element to be removed more than one hop from the subnetwork.
