from a security analysis perspective, i guess an important question  
would be if in LISP 3, TR also learn through tunneled data packets  
and MAP-Reply packets as described in the draft-farinacci-lisp-01. If  
yes, then we need to see if the threats identified in the threat  
analysis draft also apply (but it is likely to be the case, if no  
additional measures are taken to prevent them)
