Hi Nir, My thoughts... Add the validation check! It does not seem to be expensive. One scenario where is this check might be useful is to prevent identification of the OS running on the router; the assumption is that not checking the mapping is/will be atypical behavior. :-)

Could there be a security issue? Perhaps other issues? � Regards, � -- Nir Arad -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
