That seems reasonable to me. The host sent a packet to the router, and the router responded with one of its own which was received by the host. This is bi-directional reachability. In general though, I cringe at the mention of the word "conformance" in the context of IPv6 neighbor discovery, and your question is an example of why. That's probably a separate discussions though, and one which has already been masticated over numerous times before in the distant past. :-) -Seb -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
