I don't think I understand your model of how a router works. To a large extent both directions are independent. A host has to get a packet to any default router, and uses ND to figure out where they are and whether they are reachable. A router uses ND to find where a host is. If ND fails, then the router simply cannot deliver the packet. Both failures are independent. -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
