One of the reasons for more negative mappings may be some operational changes that happened first on the ALT, and then the way DDT works. When I started monitoring the beta network, all the 153.16.0.0/16 prefix was considered EID space, and a Map-Request would either return a positive reply, or nothing at all. Only queries outside 153.16/16 returned forward-native. At one point that changed, and depending on active registrations, negative Map-Replies were returned from within that block. And with DDT, I think there is even more granular information about prefix status. -Lori _______________________________________________ lisp mailing list [email protected] https://www.ietf.org/mailman/listinfo/lisp
