i.e. an unnumbered link where there is no assigned prefix, and every destination, other than link local ones, are considered to be off-link. If you want a prefix to be considered on link, such as a group of end-nodes LAN scenario, you need to announce it in a PIO (with A off if you don't want SLAAC). > Steinar Haug, Nethelp consulting, [email protected] > > -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
