Editorial contextErik Nordmark and the Neighbor That Became Stale Before It Became Unreachable, An IPv6 neighbor can become `STALE` while it is still carrying traffic, and it can enter `UNREACHABLE` while packets are still sent to its cached link-layer address. The apparent contradiction disappears once the cache is read as a record of expiring evidence rather than a directory of enduring facts.Medium confidence
