>From the discussion on draft comments, I have the following basic question:
Is a value A is assigned to either the EID space or the RLOC space? Could site X have an EID with value A while site Y (or even a non-LISP) has an RLOC (or globally routable address) with the same value A? For instance, consider deploying an IPv4 LISP site now. Could one take an IPv4 prefix already used globally by a different company/site - and use it for my new LISP site as an EID prefix? Do all the drafts always check for the IP address in the mapping database to see if it is an EID? I recall seeing some cases of checking the global routing table - but that could be bad memory at this point. Could a host in a LISP site send to an IP address as an EID and the same IP address as a globally addressable (or routable)? I am confused because "architecturally" I believe the EID space and the RLOC space are separate namespaces - but in practice in the drafts, it seems that a given value must belong to a single entity, whether it is used as an EID, globally addressable, or both. Is this clearly specified anywhere? What am I missing? Alia _______________________________________________ lisp mailing list [email protected] https://www.ietf.org/mailman/listinfo/lisp
