Configuring in compliant mode is going to be hard with our current setup. To be honest, I'm not terriably worried about it. The bigger issue in my mind is that we need to deal one way or another with multihomed hosts. An a side note, the magic option should probably contain the number 4 in it somewhere to differentiate it from other forms of LLA. -- Brooks --48TaNjbzBVislYPb Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQFE7fO8XY6L6fI4GtQRAgwkAKDOTCfsn9tep0p8Se+2u6TN+dDTrQCeLe8u sTvtImN1bJyGyuKBMq2/6/U= =oSLo -----END PGP SIGNATURE----- --48TaNjbzBVislYPb--
