Subject: [v6ops] Question re. destination cache entry in Neighbor Discovery

Hi Everyone,

I wonder if you could help with a couple of questions related to destination cache management in IPv6 Neighbor Discovery:

-          It appears from testing on Windows 7  devices that if a prefix is removed on a router to which the device is connected, traffic stops as soon as the prefix is deleted, even though the destination cache entry is not removed.  Is this behavior expected?

-          After one minute, the destination cache entry is removed.   Is there an RFC reference defining the lifetime of destination cache entries?

Regards,
