I don't understand your reply at all. My message did not concern "packets to legacy hosts". I was only discussing packets being sent to LEID addresses - no matter whether they were sent by a "legacy" host or a LISP host. My point was that a LEID address always has Locator semantics, and that so does every other global unicast IP address. Its just that if the LEID destination address is for a host in a network different from that of the sending host, then for part of the journey to the destination host, the LEID address has its Locator semantics interpreted by a new "Algorithm 2", which ITRs execute. - Robin _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
