Give up on the names and look at how things are used. As to whether something "is" an identifier or not, the main question is NOT whether it is sometimes used by forwarding functions (forwarders already use anything and everything they want to make forwarding decisions), but whether its association with a particular endpoint (at some layer) is independent of changes in topology. In the case of LISP the answer is not clear because it depends on use. Potentially it can be topology-independent, but it is expected to be used by forwarding in some site deployments, and a site might renumber endpoints within an EID prefix if they move within that site. But really, the thing to focus on is expected usage and real world usage. _______________________________________________ rrg mailing list rrg@irtf.org http://www.irtf.org/mailman/listinfo/rrg
