Ironically, the need to interact with existing hosts means that in a scope around the 'other' host (more on this in a second), the EID _also_ needs to have some 'routability' - otherwise the packet cannot be forwarded to the destination. The size of that scope varies. If the other host is also in a LISP site, it might reach only to that site's ITR. If the site is a legacy site, connected directly to the DFZ, there must be a route in the DFZ. Etc, etc. > Probably the best that we can do is to point out that the term EID > might be a bit of a misnomer. The "Architectural Perspective" document contains a fairly extensive discussion of this issue ("5.1. LISP EIDs"). There is a warning cross-reference to that discussion in the "Introduction" document ("3. LISP Overview"), although I do note that that warning is not replicated immediately below when the term EID is introduced ("3.1. Basic Approach"). Would people like to see me add an additional warning (and cross-reference) at the point at which the term 'EID' is introduced? I don't know if it's important enough to disturb the flow of the text, but I don't have any significant objection to so doing if it's important enough. Noel
