Snipped from RFC 4861 is this text: [Note, however, that a Prefix Information option with the on-link flag set to zero conveys no information concerning on-link determination and MUST NOT be interpreted to mean that addresses covered by the prefix are off-link.]

There is no means in IPv6 ND to signal a prefix as off-link! It's just that when the L-bit is cleared the host has to send traffic to the default router.

This is an RA with no PIO > (Prefix Information Option). This is not accurate. This can also be signaled using an RA including a PIO by setting L=0 in the PIO. -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 -------------------------------------------------------------------- -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
