GRAND currently focuses on 'a new address being added to the
interface' scenario. It does not solve the case of a node starts using
an already configured address after a long period of inactivity.

I guess we can add to the very end of the Section 4.1.2 (the new text):
"A node MAY send unsolicited NAs for its preferred addresses
periodically to refresh the Neighbor Cache on the first hop routers."

On the other hand it might pollute the router NC with entries for
addresses which the node has configured but is not going to use.

What does the WG think?
