If link like PPP does not have link layer addresses, there is no point in doing "address resolution". Nobody should require implemenatation to do pointless silly things. I believe trying to put SLA option on NS/NA on a link without link layer addresses is actually violation of RFC and causes the messages to be ignored. If link like PPP does have link layer addresses, normal ND rules fully apply. However, DAD is perfectly sensible. And, any other ND messages that make sense without SLA are perfectly ok and usable. -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
