Is the IPv6 neighbor cache supposed to not inlcude incomplete entries? When my freebsd box resolves a previously unknown ipv6 address with ndp it does not add anything to the neighbor cache before it gets a reachability confirmation. I have viewed the neighbor cache with ndp -a.
The ipv6 addresses in question are local, so I am pretty sure that on-link determination is not interfering. The same thing happens with both link-local and global addresses. When I ping an unused ipv6 address I do not find any corresponding incomplete entry in the neighbor cache afterwards. But, if I ping an unused ipv4 address i do find an incomplete entry in the arp cache. I am curious as to why this behavior occurs. Is it intentional? Is it by design? The reason for my curiosity is that I have not observed this behavior in other OSes such as linux and openbsd. My box is currently running.
