Stale NDP entries will generate an ICMPv6 Neighbor Advertisement (NA) if Neighbor Solicitations (NS) are received in rapid succession.
Unexpected NA informs about the reachability of the neighbor that in fact might be not reachable.
Neighbor entry being queried by the NS is in the probe state caused by the previous NS packet.
There is no workaround at this time.
Unexpected Neighbor Advertisement is no longer generated if Neighbor Solicitations are received in rapid succession.
