Quite handy. Is there any way to specify multiple tokens, please? The goal would be to replace rc.conf's ifconfig aliases and automatically use the prefixes advertised to add a set of addresses. I've tried declaring suffixes on the same configuration line the following way : slaac token ::1 ::dead:beef ::ace:cafe Or using multiple lines : slaac token ::1 slaac token ::dead:beef slaac token ::ace:cafe First uses ::1 only & second uses ::ace:cafe (seems expected after a glance at if-options.c code) BR Éric
