Noel, 

Thank you very much for the answer. I was looking for this detail in the "draft-ietf-lisp-introduction-03". 

Another question, does the response from MapServer have a cache timer associated? Or the requester can keep the response forever? 

Since you are the editor to "draft-ietf-lisp-introduction-03", want to point out that there is a typo "inferfaces" in Section 13.1. 

Linda
